Oof, fair enough! That matches the 80% "this is a terrible idea!" and 20% "oh it works with X, Y and Z rules" I keep seeing, but man it's tempting to try...

As someone trying this for netcode now, were these recent failures? Box2D and Jolt authors have both said cross-platform determinism works now with a few rules (no fast-math, no fused multiply-add, custom trig). I'd test before committing, but I'd love to know if you have any specific failure cases!
