PR 3885 is a preliminary but working implementation. Needed new tests and documentation.

>>> import re
>>> re.findall('(?i:[a-z]+)', ''.join(map(chr, range(0x10000))))
['ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz', 'İı', 'ſ', 'K']
>>> re.findall('(?ia:[a-z]+)', ''.join(map(chr, range(0x10000))))
['ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz']

The engine now uses separate opcodes for case-insensitive matching in ASCII, UNICODE and LOCALE modes. It may cause small speed up of matching, but slow down of compiling.
