Do you mean that all the packages in pkgsrc have been changed to
link against libpng12 instead of libpng, and thus I need to update
png version in order to be still able to compile stuff from pkgsrc?

If pkgsrc packages now compile fine with older png, the ABI
depend on png-1.2.9 should only be forced if png-1.2.9 was
actually used for compilation (i.e. the result binary package
must depend on png-1.2.9+ if and only if png-1.2.9+ was used
for it's compilation).

I wasn't aware it's officially unsupported. Why it's there at all
then? It's useless to have known-broken feature in.

Since it's current pkgsrc standard to bump the RECOMMENDED/ABI
depends each time random pkgsrc package needs the newer version
or for other random reasons like security issues, I don't
feel like wasting my time tracking all particular issues with
ignoring RECOMMENDED/ABI depends.

Pardon? So pkgsrc has policy "let's force all pkgsrc users update
all their packages all the time just because pkgsrc developers
are lazy to bump depends on packages which actually need it" ?

Default-build reproduceability is certainly not reason to bump
ABI depends.
