It mentions the built-in "elisp-benchmarks-run" but that doesn't
appear to be built-in on Emacs 28.

Thanks for pointing this out. Correcting this now -- I didn't realize
this was a separate package that I had installed.

Neat, I’ll have a go at running the benchmarks tomorrow, on machines I
have available :)

The benchmark's `delete-region` are bad somehow according to native-
comp:

Did you run across that at all?
