You think only two packages need recompiling? I can only conclude
that, while you may have read the thread, you did not understand it.
The best summary (in my humble opinion) is
http://lists.debian.org/debian-devel/2002/debian-devel-200201/msg00243.html
The main conclusion is this: if imlib1 (and gdk-imlib1) change their linkage
from libpng2 to libpng3, then ANY APPLICATION THAT LINKS WITH ONE OF THOSE
AND ALSO WITH LIBPNG NEEDS TO BE RECOMPILED. That's a whole lot more than
two packages.
I have tried it --- I rebuilt imlib1 against libpng3, and everything
I care about breaks, starting from the splash screen, to sawfish, to the
"Mail Check" applet.
But you needn't take my word for it: try it for yourself. You can
find the changed imlib sources and i386 debs in my home directory
on auric.

I guess you got lucky. Perhaps only gnome-help links against both
imlib and libpng.
The fact remains that we cannot change the linkage of the library
NOR of applications piecemeal. The changes must be coordinated.
In the absence of a transition plan, I see no reason to introduce
instability in GNOME by changing imlib. If you have a workable
plan, I'm all ears.

P.S. Just for the record: what specifically are the benefits to
recompiling everything with libpng3?
