While workloads will vary, Jens says, most I/O patterns are dominated by random I/O and relatively small requests.

There are so many ways to count "most" that this fact is pretty useless. Jens should just say, "some important I/O patterns are ...," which is reason enough to do this work.

I see a lot of thought wasted prioritizing things based on arbitrary "mosts": Most I/Os are reads, most files are under 4K, most computers are personal workstations.
