motion.spindle-speed-in IN FLOAT
Actual spindle speed feedback in revolutions per second;
used for G96 (constant surface speed) and G95 (feed per
revolution) modes.
Because important things don't work without it, I think all lathes
will have a signal here, whether it comes from an encoder (directly
or through a ddt) or it's just a loopback from the commanded spindle
speed (in the no spindle encoder case).
I'd go ahead and depend on it being there, if it solves a problem.
Maybe also add another note to the documentation here?
