I think we'd want to just make a hard switch to 1.8.7 and ditch 1.8.6
completely. It's not feasible for us to maintain *three* different
compatibility modes, and I don't think there's any remaining reason
not to move to 1.8.7. Every time I've heard about Matz asking people
to report any remaining incompatibilities between 1.8.6 and 1.8.7,
nobody has been able to point out a single thing.
I vote we go straight-up 1.8.7.
