Yes, there is. The old gdk-imlib1 depends on libpng2, and there are many
existing binaries, both in the archive and outside it, which depend directly
on both gdk-imlib1 and libpng2. The Conflicts is present to ensure that
users do not install combinations of packages on their systems that will
result in unusable, segfaulting applications, while allowing continued
installability of packages which depend on gdk-imlib1 without depending on
libpng2.

It doesn't. You're not forced to remove libpng2, you just don't get to keep
libpng2 *and* upgrade gdk-imlib1.

libpng2 is already gone from unstable. Any packages still depending on
libpng2 need to be rebuilt with libpng3 (libpng12-0) to be released with
etch.

These packages are already being rebuilt to use png3. This is why
gdk-imlib1 has this conflict.
