Sorry for informing you, but your sense for aesthetics is a very
personal thing.  If we really want to talk about UX, much more would be
gained by having a translatable GUI than through questionable command
renamings.

- guix pull: You "pull" a fresh set of package descriptions.  Note,
that you can't "push" package descriptions *yet*.
- guix upgrade: You "upgrade" a given user profile.
- guix system reconfigure: You "reconfigure" your "system" according to
the specifications made in some file.  Note, that this is not
inherently an upgrade -- it is perfectly fine only to change some
services, to add new ones, or to do all of those three at once.

Of course, there may come times, when you will have to explain to your
less tech-savvy family members or friends, who you've helped install
Guix, why upgrading all of your packages is such a tedious operation,
that involves this funny command line thing.  I've been there and done
that.  It all makes sense if you take a little time to
explain/understand it properly.
