Yes, and you also need to keep in mind that several developers wear
multiple hats, and contribute to CPython on a regular or semi-regular
basis.

It is also enlightening to look at the output of hg churn.  The number
of active CPython developers over the past year is not huge, and very
few of them have spoken up in this thread.
