[gentoo-dev] gtk3 useflag and support of older toolkits

Bug #420433 lately introduced the discussion again if and when we should
support older (deprecated) toolkit versions.

As for the named bug it may make sense to support it, cause the gtk3
useflag would lead to different (reduced) functionality of that package.
(but that shall not be the discussion here)

Generally I think gtk3 useflags should be avoided and only be a
workaround during migration to gtk+:3. Optimally gtk+:3 should always be
forced when available and not leading to major issues.
On the other hand... if gtk+:3 implementation is broken I would suggest
to simply force gtk+:2 without any gtk3 useflag. So we have ONE working
toolkit version.

Introducing stuff like gtk3 useflag will let users think this is about
choice, but it's actually not (gtk+:2 is not being developed any longer
afais).

Would it make sense to add a tracker for packages currently using gtk3
useflag, so this will not become a habit and only be a workaround?
