It is an accurate description. The mach ports are waited on through kqueue, and I use kqueue for all other waiters with "standard" fds (i.e. files). But my usage of mach ports (even for a partial use case) make it incompatible with BSD, and even if I didn't use mach ports the kqueue structures used by macOS are slightly different and incompatible anyways, and I don't claim BSD support anywhere. It's splitting hairs and being a bit pedantic, but you also reordered my descriptions: in the README I always say "macOS (kqueue)" and not the reverse which you incorrectly quoted. I think that makes a small but tangible difference.
