It'll stick comfortably at least through the next reboot, and possibly beyond that. It'll only become a problem when they can no longer keep her under thirty-five while still having been booted under DADT (and given that twelve issues of comics don't necessarily correlate to a year in fictional time, I don't see that being a concern until another line-wide continuity reboot).
When that does happen, as long as it isn't wildly out of place -- and unfortunately I don't see that happening in the near future -- I hope they do find some way of incorporating discrimination into her origin, as I like major superhero books to turn an eye toward social issues whenever they can. Although the DADT origin was wonderful as it allowed her to show both her need to help others while still remaining unflinchingly true to herself in one concise setup. Add an encounter with Batman to provide a catalyst for her turning her skills toward superheroing under the Bat-mantle, and it's one of the best superhero origins in recent years.
