I would expect a benefit in terms of cold-code/interpreter performance.
Do you see any benefits here?

Less run-time work for optimizers is one possible benefit, but I would expect the interpreter itself to also shows some performance difference.
For instance, I’d assume there’s less needed for run-time specialization in the Truffle interpreter, and the Truffle interpreter code being less polymorphic.
Is that the case/measurable?

Best regards
