re2 deliberately omits some features for efficiency reasons, hence is not even on the table as a possible replacement for the standard library version. If someone is in a position where re2 can solve their problems with the re module, they should also be in a position where they can track it down for themselves. MRAB's module offers a superset of re's features rather than a subset though, so once it has had more of a chance to bake on PyPI it may be worth another look.
