Being rare will not make it practical. ;-)
What I am trying to point is that considering the size of the Guix
repository and its rate, the current implementation will not scale and
the fallback will be impossible for the end-user.

Well, I do not see which features will be missing. I am talking about
making practical:
guix time-machine -C channels.scm -- shell -m manifest.scm
and not having a complete working Guix. Well, I read a paper that
mentions this command line, I want to inspect so I am running this
command. Somehow, I do not care about the others 114456 commits of
the history. And for sure "guix time-machine -C channels.scm --
describe -f channels" will not be a fixed-point.
Maybe, we could imagine an option for shortcutting the complete clone
and restrict to one specific commit.
Cheers,
