They are still the both evolutions of the same development tree, they
are the same package, just different versions. If we changed the name of
a package every time there was an API break, we would literally have
thousands of packages in the tree that essentially do the same thing,
just with different API's. According to this philosophy, we should
change the name of the package every time net-misc/neon comes out with a
new version, since it breaks API on every version.

There is no problem, gtk1 and gtk2 can be installed on the same system
at the same time, and all packages in the tree have their dependencies
set up to depends on whichever version of gtk they need. SLOTS take care
of this quite well.
