I'm in the personal opinion that, as these situations happen more to uncontrolled knockdowns (where there's no momentum cost or action use by the inflicter) that this change would be unneeded. A reactionary effect that costs no momentum or actions has that exact advantage- and should have a suitable disadvantage of not always being the best time to use it, as opposed to decisions made on the part of the player that are controlled, but thus cost more.
