That's a reasonable fear.  I'm actually fairly confident though.  My
changes are to make the internal workings more (nearly completely)
opaque, meaning that future changes don't affect the ABI at all.  The
API can then be extended (new functions) but should not need to be
changed in a non-backward-compatible manner any time in the near
future.  I'm perfectly happy (eager, in fact) to have others' eyes on
these changes to make sure I'm not missing anything, but this is
fairly straight forward stuff even though the patch will appear huge.

Understandable.  I'll keep working on this until I'm told that it's a
no-go.  Hopefully I won't have wasted my time, but I'd rather work on
it now with the expectation that it'll be able to go in, rather than
forever have to deal with the status quo. :-)
