I'd say it's "genuinely incompatible" if it breaks FF 10 or its own
functions don't work when force-installed, but "nominally
incompatible" if it just has "maxVersion=9.*" in its configuration.
For me, that's a big difference!

As it turns out, I unpacked the old & new XPI files, then unpacked the
jars in them, and found 2 or 3 small-looking changes (besides the
maxVersion line), so maybe....
