There are at least three good reasons to make sure this can enabled/disabled by a flag:
- We have to anticipate that introducing new keywords will cause some compatibility problems. New language standards that introduce new keywords can be disabled using `-std=<something earlier>`. We shouldn't let this bypass that just because it's an out-of-band addition to the base language.
- It seems likely to me that this feature will be target-restricted.
- It seems plausible to me that development of this feature might continue past the Clang 7 branch date, and we shouldn't release a compiler with significantly-incomplete features on by default.
That said, when it's ready, I think it should probably be on by default on the targets that support it.
