For the record, the OP (Phillip) was thinking 3.5 or later. I'm the one who made the assumption he wanted this in 3.4, and he immediately corrected me.

Also, I get the impression that he wants to define a new API which doesn't match any of the existing libraries, and not add anything to the stdlib until one of the existing (fast) libraries has an adaptation to the new API, which means it's clearly not an immediate-term goal. He just wants to get some consensus that this is a good idea before starting the work of defining that API, finding or building a reference implementation in pure Python, and convincing the existing library authors to adapt to the standard API.

If I've interpreted him wrong, I apologize.
