... the same thing can be said about subcommands of "git refs", all
of which you have to remember.  I am not sure if this "everything
under "git refs" really makes much difference.

So?  That still does not indicate adding yet another command to do
it is the right solution to the discover-ability problem.  Instead
of shifting and moving things around, reimplementing things to risk
introducing new bugs, wouldn't it be more productive to spend effort
on improving the documentation and possibly filling the gaps of
features?

Thanks.
