It would be helpful/essential for verification tools to have access to the Yul ASTs that are generated throughout compilation via Yul.

I'm wondering - is it really essential or would it also work to run solidity in yul mode and output the ast?

Which ast would that be? What I'm imagining is that all the Yul compilation steps could be exported:

  • Solidity -> Yul
  • Yul -> Optimized Yul
  • Optimized Yul -> Dialect Yul (if applicable)
