[Question] rewrite rules: merged into upstream or maintained out of tree

[Stonesjtu]

Hi there, onnxscript is super powerful in terms of fusing operators. I've implemented several rewrite rules, could anyone give a guideline on what rewrite rules should be in the onnxscript main repo. Or I just make another private repos holding these rules.

e.g.:

• fused Conv + Mul + Add into Conv
• fused HardSidmoid + Mul into HardSwish

You are welcome to contribute all of the above to this repo. Thanks!
