Yes but core Python doesn't have any other true concurrency mechanisms
other than native threading, and they're too heavyweight for this
purpose alone. On top of this they're useless for Python-only

Too far. It needs to be now. The downward spiral is already beginning.
Mobile phones are going multicore. My next desktop will probably have
8 cores or more. All the heavyweight languages are firing up
thread/STM standardizations and implementations to make this stuff
more performant and easier than it already is.

This doesn't apply to "enabling" features. Features that make it
possible for popular stuff to happen. Concurrency isn't popular, but
parallelism is. At least where the GIL is concerned, an good
alternative concurrency mechanism doesn't exist. (The popular one is
