New patch attached that revises the preamble to include an explicit goals section that links out to the issue tracker stats page that demonstrates that we have a problem with a lack of core reviewer time.

Much of the rest of that section has been moved up from its former location in the "Limitations" section, but some of it is new (in particular, the paragraph specifically encouraging people to look for ways to spend work time on mentoring new contributors).

The preamble is already really long (and I'm definitely open to suggestions for making it shorter), so I *didn't* try to include an explanation of how the inequitable distribution of free time means that getting more paid involvement in core development should also help improve the diversity of the core reviewer list. The gist is that as more opportunities exist to pursue CPython development as a paid activity (even if it's only one part of a larger job), then that helps remove "has lots of spare time for volunteer software development" as a gating criterion for becoming a core reviewer.

I'll ping the folks I was talking to off list to see if they'd like to comment here, or otherwise provide feedback on the new draft.
