We are getting off topic here.... I was suggesting we separate our HAL and cnc stack with the idea of possibly using MK HAL.
NML is part of the cnc stack. That would be future work, I'd someone wanted to tackle it. Though just the act of splitting hal from CNC without adopting anything would make future work easier.

If it doesn't have some needed process is it not able to be extended?
