And explain what it's about. I don't consider myself an absolute
beginner with Guix, but I don't understand what's going on here!

OK, now I do a well... but should users need to understand the
developers' git workflow?

Ultimately, the issue here is that guix works on the implementation
level of git commit references, whereas the development process uses an
abstraction layer on top of it. Maybe "guix pull" and "guix
time-machine" should acquire some built-in intelligence when given a tag
instead of a hash? Issue a warning when an inappropriate tag is given,
and suggest a correction?

Cheers,
  Konrad.
