It depends. Read what Schneier wrote right before they announced the SHA-3 winner:
https://www.schneier.com/crypto-gram-1210.html#2
There's really no security reason not to use SHA-2, and in fact it's probably better, as it has been more widely studied at this point. But that part is easy; it's the compatibility switch-over that's hard (we could also even parameterize the hash, but that has some annoyances, too).
