As I understand you mean ‘--’.  I guess it's required, because with
‘system’ you could do additional ACTIONS as ‘guix system --help’ says.
ACTIONS includes more OPTIONS.  It will be a mess to include all not
related OPTIONS from ACTIONS (really long ‘--help’).

Yes, as I remember there is no command to clean up system generations.
At least I didn't find one.  So I wrote a script to remove system
generations older than 14 days (second line) and remove guile packages
older than 2 weeks (third line).

exec guix package --delete-generations=2w

Probably no, because it's not a bug.  Just a discussion about
improvement, which guix-devel mailing list is enough.
