I'm curious, after you did `guix pull --allow-downgrades -C`, did you
use `guix show foo` before reconfiguring, in order to check if the pull
had taken effect?

Also, did you pull and reconfigure as the same user, with the same
privileges? Remember that your "view" of Guix (i.e. `guix pull`) is
per-user.

That's my understanding as well.
