When I'm asked to review or test a plugin, or inspect it for suitability,
any plugin that leaves a mess behind will get very low marks. Unfortunately,
it'd be quite difficult to determine which options and tables came from
where. The only true solution here is to educate plugin developers to use
deactivation and uninstall hooks properly -- "Leave No Trace" is an
excellent mentality of any plugin or feature -- and do what it can to limit
the number of options and tables needed.

Our philosophy is plugin over core option, of course, and this seems like a
perfect candidate for a plugin.
Generally speaking, core plugins will come not only out of a need, but
proven demand. While I don't see it here, it could of course gain traction
