Why do we need a separate flag?

[caitp (gmail), 2015/02/25 00:00:24]

See the answer I gave to Erik --- If spread-calls and spread-elements are behind
different flags,  it seemed nice to have a third flag which would implicate both
of them (also, it would be convenient to put any self-hosted runtime support for
both in one script).

If that's not cool, I'll just get rid of it

[rossberg, 2015/02/25 14:28:18]

Well, since they currently imply each other, the separation doesn't really
exist. :)  But yeah, I don't think we need feature subset flags.
