Development Gentoo for developers

True, but while (for random example) Debian has libwxgtk2.4-1, libwxgtk2.4-1-contrib,
libwxgtk2.4-contrib, libwxgtk2.4-contrib-dev, libwxgtk2.4-dbg, libwxgtk2.4-dev, libwxgtk2.6-0,
libwxgtk2.6-dbg, and libwxgtk2.6-dev, Gentoo has one package, x11-libs/wxGTK.

Packages that never leave ~arch have little to do with lack of developers (though that is
something we need to improve on).  All it takes is a user request to have the package stabled
on their architecture.  The stabilizing process is handled by architecture groups rather than
the package's maintainer, and so isn't held up in the case the maintainer is MIA.
