Yes. I'm a little busy right now, but I hope to get around to it on the weekend or so. Maybe by that time Forge will be "ready enough" for this type of mod (nearly pure Mixins) as well.

Edit: I'm leaving this open for now, in the hope that it stops people from opening more issues about it.

I've published a beta build for 1.17 (only on Fabric for now), see:
