I think we gained very little as far as add-on compatibility goes by
freezing as many APIs as we did. Only binary extensions have anything to
gain by the level of freezing that we used, script-only extensions will
not be affected.

I don't have any data on how many of our top-extensions have binary
components though.

The cost of freezing all interfaces was quite high. It uglified new code
a good bit as well as cost in performance and memory (though probably
not to a significant extent).

This was sort of ok when the changes went in to a branch that is
eventually going to die. It would suck a lot more to do that to
mozilla-central where we'd have to clean up the mess later, or live with
it forever.
