I doubt you'll be able to get rid of static types entirely, due to the
usual issues with C API breakage. And I'm guessing that static types
make up such a tiny fraction of the address space that merely tweaking
the percent up or down won't affect performance.
But your proposed new API would make it *way* easier to migrate
existing code to the stable ABI.
