If we had a carefully defined interface between PLs and the core, then
we might have some reason to think it'd stay stable. But we have no
defined API, and thus there is hardly any chance that PLs not maintained
with the core won't break. I'm certainly not willing to agree that
anything the existing PLs happen to depend upon is frozen.

Hmm, that could be a problem all right ...
