That would be too strong.

This is ridiculous. If there are functions that adhere to the contract 
of completing-read-function, and tmm can't work with them, tmm should 
use completing-read-default, and that's that.

I'll install the submitted patch in a few days if someone doesn't beat 
me to it.

You are mixing up concepts right and left. E.g. APIs with their callers.
