It's a great start, but we need to figure out what precedent to set. We can do most of that in another PR, but for this one there's a few changes I'd like to see like 1) rename the file, and 2) get rid of the grouping inside the benchmark. It's unnecessary. Grouping tests within a benchmark function is more for comparing a single benchmark sliced in different ways, like I did in my ordinal crate I linked to. With just one benchmark, a group is just distracting and more code that partners need to needlessly write.

A few nits and otherwise good to go.
