This example for me suggests we'll need to have some kind of process of
defining what tags should be used for what things, similar to how we have a
process for global USE, mostly, because inconsistency is a bad thing here.

Because looking at this example and the results of `eix -cS terminal`, I
see lots of things that may also be ambiguously tagged "terminal" due to
being a terminal based application.

Thus, either "terminal-emulator" or "terminal-app" or similar tags seem
necessary.

emerge --search tag:terminal-app tag:jabber-client  ( or similar ) should
thus result in net-im/mcabber

And now that we're starting to flesh out mock tags that may make sense, it
quickly seems we'll eventually want some kind of tag hierarchy.

But as long as the tag is restricted to [A-Za-z-]+  or similar, we should
have enough syntactical space to add a hierarchy in later if we find out we
need it.

For the sake of avoiding bikeshed, we should avoid hierarchy until we've
proven tags are useful and have discovered we really need hierarchy. YAGNI
