Although Russell's approach is a build breaker for those platforms that have
not yet made the switch, that does provide an incentive for the platform
maintainers to update their code. If we settle for a legacy solution it will
probably sit around forever.

Given that we're now past -rc2, it might be best to wait until the next
merge window to introduce the #error logic, so the LEGACY solution could be
a stopgap for 3.2.
