Better controller support? Controllable + Parcool (1.16.5 or any future)

Hi! I use a controller to play minecraft via Mr. Crayfish's Controllable mod. (Kb+m is not an option, disability/accessibility related)

I also run a minecraft server! I believe my players would enjoy this mod, but we have the rule that nobody should be excluded via the inclusion of a mod. Each of us has needs and issues, and so we try to make a space we can all enjoy.

The mod may as well not work at all with a controller; things half work or don't work at all, and it wasn't until I accidentally mistyped that I realized that double tapping would dodge roll me on a keyboard.

So I was hoping maybe you could either find a way to better universalize the control inputs (so that Crayfish's mod can hook it via custom inputs, as well as other mods) or support that mod directly? I have time to test things - ideally 1.16.5 as that is our server version target - and I have a background in computer science to help debug.
