At 100 inches per minute it owrks, what about 200, or better yet 400
or 600? That's the speed that routers need to run to prevent
bitburn. Then there are lasers and I blieve some of the plasma
machines want to be cutting over 200 ipm on real thin material They
want to rapid as fast as possible to get from one side to the other
of a 4 x 10 ft sheet of material, at 100 ipm it takes almost a minute
to return to home from the far side of the table.

So the answer is that "NO" the present limits are not satisfactory
for all , and maybe even many hobby uses.
