Not exactly. This particular issue was more of the variety of - we
add some checks that earlier version of toolstacks did not have. And
as such we fail to do the operation _unless_ a force is given.

But all of this kind of falls under a seatbelt function - if the user
knows what he or she is doing could be bad, well - if they know what
they are doing then they can go ahead.
