Hey @modulargrid, all these ideas are just things that come to me while I clean-up each day. It's by no means a requirement or a request; merely suggestions. As always, I'd be up to discuss these or any similar matter to a larger extent. A clean DB is what we're both aiming at! :) And by the way, I know full well that implementation is a totally different issue, so again, no pressure whatsoever.
I think that being able to Force Delete a module entirely could be an abrupt yet functional method, at least for mods? Maybe add an option list when deleting to send a message to the original poster (OP) so that they get informed of what they did wrong. Or maybe not.
Still, if we can't have a merge I, for one, vote to delete duplicates of modules that are now set up as hidden.
