I'm not sure I'm on board with that as a releaseable default, but there
certainly would be an argument for turning it on from now to say mid
beta, so as to improve test coverage. I think we've done similar things
in the past.
I don't understand however how that doesn't break the regression tests?
Surely we've got lots of EXPLAIN queries that would change.
