On a recently installed system, I ran guix install coq -n. Guix told me it would download 270 MB and do 4 hooks. Guix install coq however told me it will 521 MB (which it did) including a lot more packages (including coq:ide),the same 4 hooks with different store hashes and additional grafts. This was quite unexpected :)
Once coq is in the repo though, guix gc will remove coq:ide and dependencies, and re-installing coq in a new profile will not pull coq:ide in anymore. Note that coq was grafted.
