One last thing...  This seems to be a userspace ABI change.  What
are our potential issues with users of this ABI?

It's not that costly to keep the code, though dropping the docs or
putting a depreciated note in them is probably a good idea.  Hence
I'm not totally convinced the risk of a regression is worth it.

If we think it's the sort of change no one will notice, then
fair enough we'll give it a go and cross our fingers.

Thanks,

Jonathan
