I'll keep an eye on this and reopen the bug if it feels like usability has
deteriorated.

That sounds reasonable. I'll wait for the release with that and report back if
there's still a problem.

I don't know where in the stack this responsibility could possibly belong, but
it'd be nice to have a way to let users know about these sorts of changes
(being able to lift your finger in between a move is a feature people would
appreciate, I'm sure).
