I'm ok with this one and it also has support from Cinder PTL.
It does introduce a new config parameter but default preserves old behavior.

Missing feature parity in drivers is a bug, concern with this patch could be a size but most of it comes from tests and utils, risky change is only what doesn't work anyway.
With this arguments, I hope Nova PTL will reconsider his -2.
