I recently marked a PR that rewrites the `/capabilities` endpoint in Go as ready for review (https://github.com/apache/trafficcontrol/pull/3870) and with it added handlers for PUT and DELETE. That means that `/capabilities/{{name}}` will no longer do anything that `/capabilities` does not, so is it alright if we deprecate it?
There's also been some discussion about deprecating the ability to create/modify/delete capabilities at all (mostly on that PR itself, atm). I'd like to answer my above question before we get into that, though.
