The issue was introduced by4df75e5and seems we just need to explicitly add new keymap item now. There is still some difference from old behavior, which is planar transform is using precision movement sincee138cdeand here i don't see nice solution currently: the change was requested here in the studio and it's just a conflict in picking shift key for something which is not supposed to be accurate. At least now it's possible to invoke planar constraint and simply unhold shift.
