This is what GTK+ does. libgtk-1.2.so.0 and libgtk-x11-2.0.so.0. GIMP
does the same thing as GTK+.

No, you misunderstand. GIMP 2.0.0 will provide libgimp-2.0.so.0.0.0. GIMP
2.0.23 will provide libgimp-2.0.so.0.0.23. ABI will be maintained for the
the 2.0.x series (and possibly the 2.x series, if we decide to do that).

There are no ABI guarantees for 1.3.x since it's a development series.
As Sven said, we do break it. It is a development series, so you just
have to deal. When it hits 2.0, that's a stable series, and the ABI
will be maintained.

Note that GTK+ 1.3.x bumped the major so number at every release too.
