Ha I did consider that! But 70x is plenty fast enough (we still have to query an actual database!) and the parser runs in a shared process on untrusted input, so it wasn't worth the security risk
If we don't care about inspecting the output, why don't we just replace the Rust compiler with something that generates assembly from Rust source, and then cross check the output with a few million random Rust programs?
Surprised anyone gets an interview there. My resume matched the job requirements pretty much exactly with 11yoe and I got an auto rejection mail at 1am.
