Yeah, I think that plan is quite out of date. I'm not sure why GRBL was mentioned, it doesn't seem to be particularly advantageous for Deltas, and the core algorithm from GRBL is now implemented in a lot of other firmwares anyway.
The idea of writing a super new firmware that works for any type of non-cartesian kinematics, and takes advantage of the ARM processors is still a good one I think.
