Careful to only do it if in fact definitely scaling. Animated GIFs are
in use on lots of page on en:wp, for instance, when there's reason to
put a small animation right there on the page rather than a click
away.

ImageMagick is a Swiss army knife - it does everything and isn't the
best at anything. I would be unsurprised if there was a tool to do
this specific job much better.
