Yes; packages tagged uitoolkit:: aren't libraries at all, so perhaps
they should get Descriptions that say things like "Xlib UI" rather
than "X library".
 
The "classic" use case for uitoolkit:: is "have you got an app like
this one but in ::gtk?"; the role:: tags are talking about different
kinds of dependency package.  The other two I'm not so keen on.

So what does devel::library mean?  It's either automatic for
role::shared-lib, or for role::devel-lib, or both, but I can't see
which, and either way, I'm not going to bother applying such a tag.

There may well be libraries where the X-ishness is more or less the
only thing distinguishing it, but then again, its not clear whether
anyone would be doing such a search.
