On the other thread I suggested to not release 5.10.1 as-is (originally I was suggesting the revert of that feature).
As for making stable faster, the ES FIM fix is the only relevant change from 5.10.1, it's localized and the change minimal, so it doesn't seem necessary to me to wait more due to it.
I think accepting other unknown issues from localized stuff is ok, otherwise we would never release. I would only block/add time if the fix/change is on core functionality which affects everyone.
