In particular, doing it this way signals our library users to get in touch about what they need from such APIs *before* we actually change the code.  Thus they get a chance to avoid hitting the performance regression and/or other limitations that we're quite likely to see when we eventually do reimplement the compatibility APIs in terms of the new ones.

Sounds good to me.
