This is what I meant.

Start fixing these issues from scratch doesn't make much sense IMHO. We could "extract" the fixes from regex and merge them in re, but then again it's probably easier to just replace the whole module.

While this is a good thing it's not always doable. Usually someone reports a bug related to something specified in some standard and only that part gets fixed. Sometimes everything else is also updated to follow the whole standard, but often this happens incrementally, so we can't say, e.g., "the re module supports Unicode x.y" unless we go through the whole standard and fix/implements everything.
