The problem was that they were overly handy so I tried to avoid them in
benchmarks/ after being burnt too often.

Nah, it's a drop in the ocean compared to writing the benchmarking
framework / integrating into an existing one like ezbench.

I dream one day we will get microbenchmarks as part of CI. Not only
would that require a radical overhaul of the benchmarks/ but a
substantial investment of hw & maintenance. In my dream, I also have a
vision of like-for-like comparisons against other drivers.
