Coming from Conda package manager, it took me some time to understand;
because the Guix terminology was not what I was expecting from the
Conda terminology (in conda "guix environment" does not exist, and
"guix profile" is called environment).

Profile as persistent environment clarifies, IMHO.

Is it possible to list all my own profiles?

I agree that "guix pull" should be split into:
 - "guix pull" which actually pulls and builds derivations
 - "guix log" which lists, switches or deletes the pull generation

For example "guix log --news" seems better than "guix pull --news".

I am not sure to understand this point. What do you mean?

To me, "guix package" manipulates transactions (states).
i.e., "guix package –-roll-back" roll backs a transaction of a profile.

  The command provides the obvious install, remove, and upgrade
operations.  Each invocation is actually a _transaction_: either the
specified operation succeeds, or nothing happens.  Thus, if the ‘guix
package’ process is terminated during the transaction, or if a power
outage occurs during the transaction, then the user’s profile remains in
its previous state, and remains usable.

Therefore, from my opinion, the UI seems good enough here.

All the best,
