This can be handled with wrappers, at install time. Ugly, but workable.
Jim's idea is very suggestive, though:

This still doesn't help to address the "fine-grained" (per-module or
per-file) control issue, right? Unless you complexified the syntax.
You could allow includes (from a site library of character set
definitions, not arbitrary files), inline table definitions, and a
file or module to table mapping.
Since this would a under control of the site (distriubtions could
supply examples, but not install them where Python would pick them
up), maybe such complexity would be OK? I believe most people's file
000000-1FFFFF # intersection of the full Unicode range and PEP
# 3131-permitted characters
(where DEFAULT is a special table used by default for files not mapped
to another table).
How about per-user overrides?
