Ah, nevermind; I looked up the spec pages;

"One GIF feature that PNG does not try to reproduce is multiple-image
support, especially animations; PNG was and is intended to be a
single-image format only."

Having more than one image in a single file, for the purposes of
favicon.ico, is not a stupid idea. So if you really want to do things
well, you're still stuck using Windows icon resource files.

And who cares? It's a bloody file format, and it's well-understood. Just
because MS has been, is, and will probably continue to be an
overbearing, illegal, manipulative monopoly doesn't mean we can't reap
the fruits the of their labour.

I don't believe MNG is widely-supported enough for use as favicon.ico.
