I think it is a good idea but the change is more than just oneline. ;-)

I agree with Ludo: the change requires communication.  Something like:

 1. Blog post.  Something like that [1], a bit extended with a Migration
    section.

 2. A news (guix pull --news) announcing the sunset date.  And probably
    pointing to the blog post (or elsewhere) for helping the migration.

 3. Optionally emit a warning when the daemon is “too” old.


I agree that the extra space can be annoying.  In the same time, user
experience matters more, IMHO.

Cheers,
simon
