If anyone is thinking ... ooh -- cheap fixed gear wheel ... this won't work for that.

From a 1/24/06 post to the Bicycle Restoration YahooGroup, the late Sheldon Brown explained it this way:

Nope, won't work. Those clusters weren't "fixed" they were just
stiff freewheels. This was a safety feature. If you were to catch a
trouser leg, shoelace or appendage in the moving drivetrain, the
stiff freewheel would slip, avoiding seriously nasty results.

Shimano called them "friction freewheels".
