We can't just make Tor Browser stop accepting obfs2 because some people are using obfs2 bridges right now. But we shouldn't add more people to the set of users of a broken protocol.
Obfs3 is also "broken", it's just that we haven't yet seen a DPI box do it IRL. If you want me to only hand out the holy grail, I'm never going to hand anything out.
The holy grail will never exist, indeed. I fail too see why this would be a reason to continue giving out solutions that are known to be bad when they have suitable replacement.
