Slightly rewrote this paragraph. I don't know how to reference index
entries (if it possible at all), so I added anchors for them.

Now it should be clear that a -configuration record is preferable as a
service value, lists and alists are special cases for auxiliray
services and shouldn't be used in most cases.

Saw it, I'll try to review and comment on it, when I'll get some spare
time. I'll keep this comment for now, and after the section about gnu
service configuration module is merged, we will add links to it and
provide more info and examples on implementing actual configurations.

More flexible comparing to just one package field, because it makes it
easier to define a configuration for software requiring a few packages
like docker.

`docker-package` is a good idea, which makes it very clear what the
content of this field should be, however just `docker` should be enough
we already have a type information for this field in documentation and
this pattern is already applied in a few dozens of different services.

Added a footnote, provided more expressive examples
@code{bashrc} for @file{.bashrc},
@code{bash-profile} for @file{.bash_profile},
@code{tmux-conf} for @file{tmux.conf}, etc.

I find this pattern purely-established (content vs conf vs options),
unclear (you can never know where this extra content will be inserted
until you take a look at implementation of serialization function) and
uneccesary (we do not need extra-* fields because we can add any
extra content using G-expression inside our primary configuration, see
sway example below).

Kind of. See guix-default? for home-bash-service-type. Also, fields like
aliases and environment-variables are of the same category I describe here.

Added them as an example of such fields.

The good examples of the bad behavior are alsa and nginx service types,
they always provide some boilerplate with reasonably good default
configuration, but you can't alter it by setting some fields to #f or
some other values.

For nginx it's only partially true, you actually can use `file` field,
but it will alter the effect of all other fields and will just use the
file as nginx.conf, kinda conforms what I'm asking here, but makes all
other fields useless.

Added the following explanation to this item:

Toggle snippet (7 lines)
For example, setting @code{guix-defaults?} to
@code{#f} and @code{aliases} to @code{'()} will give user an ability to
control the content of @file{.bashrc} solely by setting the value of
@code{bashrc} field.

This is mentioned below, as well as the problem of closed-world
assumption. Software should be fully configurable with field for
respective config file, escape hatch should be a part of this field.

Escape hatch is necessary to allow to reuse already existing
configuration, but not to provide configuration, which can't be
expressed by respective configuration field.

JSON is a subset of YAML, so having a serializer for JSON makes it
possible to generate configurations for many YAML-flavored applications.
However, it maybe not that clear and important. Will remove it.

Yes it is more Scheme-flavored, but it doesn't mean good. I can write a
good rationale on this topic, but will do it next time, now I'll just
give you an example, which should be relevant to you: Imagine writing an
importer (for `guix home import` for example) from XML to SXML, now
imagine that instead of SXML we have Scheme-like configuration. It
hours and days more work. Implementing and maintaining such
Scheme-flavored configuration is a big pain, especially if software
still changes and config options isn't stable yet.

Moreover, it doesn't give too much benifits, some compile time checks
with quite poor type system, which gives some safety feeling. There are
better solutions for that like clojure.spec in Clojure. Also, event not
having guile.spec, the same checks can be implemented with basic pattern
matching.

IMO, it not worth it to stick to Scheme-flavor for configuration fields.

home-sway-configuration is complete and it won't take much time to
upstream it, when we finish with this guideline.

It's @, not @@. You are right, use-modules is prefered in most cases,
but for this example I think it's ok.
