Being able to set which behavior you want in a (?XXX) flag at the start of the regex is valuable so that applications that take a regex can support the new syntax automatically when the python version they are running on is updated.  The (?XXX) should override whatever re.XXX flag was provided to re.compile().

Notice I said XXX.  I'm not interested in a naming bikeshed other than agreeing with the fact that NEW will seem quaint 10 years from now so its best to use non-temporal names.  COMPAT, VERSION2, VERSION3, WITH_GOATS, PONY, etc. are all non-temporal and do allow us to change the default away from "old" behavior at a future date beyond 3.3.
