I know of a fellow that worked on a vertical sliding saw professionally and
stopped it with the side of his thumb, for years. One day he got a carbide
blade installed and forgot.

The fire was in the last half of his thumb.


Watch your working habits. Environments change. You may too... in body
shape.

I would prefer powered off/normal on, because the operator would get
used to the blade always braking and in the case of a solenoid
failure, the blade would not coast.

I would also think an assembly with wheels applying just a little
pressure to the sides of the blade would make a decent passive system.
It would be just enough pressure to slow down the blade in a second or
two and not enough pressure for the motor to even register the
resistance.
Think about how little pressure it takes with a scrap piece of wood to
stop a coasting blade.
