bug#49265: 28.0.50; repeat mode feature request

[Ergus via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Is it possible to add a command to get information about the commands
that have a repeat map? Basically something to know the commands with
some associated repeat like list-repeat-commands or describe-repeat or
so?
