‘guix pull’ already provides high-level “package news”, but I agree it’d
be nice to have a way to convey “system news” and perhaps free-form
messages like Debian’s change logs.

I suppose we could use some specially-formatted Git commits to pass
messages to users.  I’m afraid it would be hard to get those messages


Note that the GDM change could also have been addressed by fixing
‘modify-services’ to report about unmatched service types, for example.
