If we're thinking of committing something that is known broken, I would
want to have a clearly defined and trust-inspiring escape strategy.
"We can always revert the patch later" inspires absolutely zero
confidence here, because in a patch this large there are always going to
be overlaps with other later patches. If it gets to be February and HS
is still unshippable, reverting is going to be a tricky and risky
affair.

I agree with Heikki that it would be better not to commit as long as
any clear showstoppers remain unresolved.
