I don't see HAL and NML as doing the same thing, and I certainly wouldn't propose HAL pins for the task planner. Halui serves a specific need - it lets physical buttons be used to control EMC instead of on-screen widgets. HAL pins are mostly suitable for conveying state information: is the button pressed, has the switch been hit, where is the axis, what voltage should the DAC be putting out, etc. It is not a substitute for a messaging system. I've never been particularly fond of NML, but HAL is not a suitable replacement for it.
