How does this affect me when I'm compiling packages
with older png (pre-change) ? The older package doesn't
link against libpng12.

IGNORE_RECOMMENDED didn't work for me in past, and so I don't
see how USE_ABI_DEPENDS would. Package authors depend
in RECOMMENDED bump, and after I got difficult-to-track
compile failures, I stopped using IGNORE_RECOMMENDED.

What is needed for png is to force the ABI_DEPENDS
if and only if the newer png package is actually used
for compilation.
