By “information in the buffer”, what do you have in mind?  There’s
highlighting of installed packages, and marks.  Am I missing something?

Pressing ‘g’ removes marks and updates highlighting.

What if the operation fails?  For instance, you carefully select a bunch
of packages to install, and then the operation fails because of some
transient networking error, say.  In such a case, the *Guix Package
Info* buffer should *not* be updated IMO, because that would mean losing
all the marks for no reason.

WDYT?

Not commenting on the elisp code, you’re the master.  :-)

Thanks,
