It's hard to get an exact count because the names are so common, but I'm
seeing <10 packages on codesearch.debian.net that might be affected, and
it's quite easy to fix (s/bits/uint/g).  My experience is that we routinely
"break" extensions like this in new major versions, too.  So, I'm not
convinced we need to do any kind of backward-compatibility work.  In any
case, we have a lot of time between now and GA, so if a bunch of angry
extension authors come to my door with pitchforks, we can reconsider.
