I would doubt that, but in any case I don't think the specific degree of
brokenness is the issue; I don't see the problem with having flags for
functionality that is still under development.  -fnew-abi comes to mind.
Or, more similarly, -fssa.

I agree that this flag should be documented, but I'm not sure all flags
should be; is it actually useful to say "here's this flag, don't use it"?
