Granted more manageble for code I maintain myself, but it doesn't eliminate the problem in theory.

I think it ultimately depends on what 8.1 is intended to be when it is released: a drop-in upgrade in 8.0 environments, or a major step like 7.x to 8.0? If it will become Pike 9.0 and introduce a bunch of other incompatibilities I'd be more open to that change, but not otherwise.
