I think I won't find much enthusiasm in this project by majority also !

But I don't think I overestimate speed (and when I mean speed I don't talk about just motor speed) it is important in many reasons.
This is a must when it comes to overall "responsiveness" of complete system.

I agree that there are many exciting projects out there like LinuxCNC (that I'm currently using), fluidNC, Marlin etc. And I won't discourage anyone from using it.

But still they don't provide this "great" experience that I'm looking for.
-they don't use full spi control over trinamic motor drivers (MODE 1), they use (MODE 2) instead, that only allow to control current and chopper of this motor driver.
-this approach would force them to rethink and rewrite motion calculations and control (most likely they won't do this).

Have a nice day !
