One would like to have a speed output from the drive but there isn't one.

Should be possible to get rps or rpm in the frequency output
by setting proper scaling factor in frequency-scale. 
Have not tried it, though.

doesnt enc-pos provide an accurate speed.

I'm not sure on that. pos = position so it implies reading a linear scale when you have a spindle, you want to measure RPM or RPS which a frequency resolves to with appropriate scaling. 

pos is of course the number of rotations since zeroing on index. This is the main driver for
the synchronized move, the z-axis is being forced to follow pos.

Rotational speed isn't mandatory, but convenient to have.
You use rotational speed for the at-speed pin and is displayed in the gui.
I guess enc-frequency-scale should be set to 1/2000, so 0.0005, for rps.
For rpm 1/(2000*60) = 8.333333e-6.
