+1 from me (SRE needs this, and it doesn't really make much
sense to add unicode tables to SRE just because the built-in
ones are slightly incomplete...)

how about this plan:

-- you add a Py_UNICODE_ALPHA to unicodeobject.h asap,
   which does exactly that (or I can do that, if you prefer).
   (and maybe even a Py_UNICODE_ALNUM)

-- I change SRE to use that asap.

-- you, I, or someone else add a better implementation,
   some other day.
