Warning

These results are subject to substantial noise because GitHub's CI runs on shared machines that are not ideally suited for benchmarking.

Looks like this is a 12% performance hit if I just loosened the type constraint. The function barrier is probably a better option, then - with that I see a marginal improvement over the results on the master branch.
