This is only a change to the default shortcuts. If you had the shortcuts customized the customizations will remain and continue to take precedence.
The rotate tool is due for a complete overhaul, which is actually why it didn’t get that much attention this time around (it needs a rewrite, not just some QoL changes).
Moving in the plane of the screen is likely outside of the scope of the current Studio draggers. Planar drag (drag on two axis at once) is actually something I’ve prototyped but it will take more work to happen. It would likely have to come alongside changing the move handles to not being double-sided, which is a big change.
I can’t speak for details on those things since it’s not my area but I do know that the top ask in light range does have active work underway on it.
