Python is a poor target for compilation, even the best JIT is never gonna make fundamental design flaws (that some may consider beloved features) disappear. It's never going to give "good" performance.
In my view, the right course of action is to specify an official strictly typed subset of the language with compilation and static analysis as the justification, then implement both JIT and AOT on top of that. Legacy code can be rewritten or thrown out in phases, C extensions can be ported.
Of course, any such proposal would invite monumental amounts of bikeshedding, which is why it wouldn't get far, much like the JIT proposal.
