I'd *really* like to know why that is the case.

I've recently been mentoring two experienced developers: Gus Goulart and Jonathan Gossage. Initially, when their momentum was highest, every day at least one of them had non-trivial questions to ask and/or PRs ready for review. I attempted to be highly responsive to allow them to progress unhindered, and found myself spending at least 30 minutes on this nearly every day. I now spend less time on this simply because their momentum is reduced, partially because at one point I was not able to keep up with their progress.
Most existing core
developers didn't need "a good amount of time" to be spent "nearly
daily" on their mentoring to get them up to speed.  Instead they
progressed slowly on the contribution curve, with due feedback from
senior core developers, but without requiring extended attention.

True, but this process is not suitable for many, and it does not seem to currently be yielding as many regular contributors and core developers as we'd like.

My personal experience is that it took me over a decade between beginning to contribute to Python to becoming an active core dev. I believe that that could have taken just a few months if I had had a mentor.
Contributing to a large mature project like CPython requires dedication
and significant prior experience.  If someone needs a large amount of
hand-holding then that's a bad sign IMO.  There are much simpler and
more approachable projects out there if they'd like to learn
contributing to open source software.

There appear to be many experienced developers interested in becoming contributors (and possibly core devs down the road). The two I'm now mentoring are such; they don't require "hand-holding" in the sense of more junior developers. No other core dev seemed to be available for mentoring them when they first asked for mentoring.
I'd also like to know what the current outcomes of the "Core Mentorship"
program are.  How many core developers or seasoned contributors did we
get from it?  The core-mentorship mailing-list has been existing since
2011, so we should have ample experience by now.

I'm looking for this info too!
