I don't entirely understand why, possibly excepting how little-used
they always were (I think I'm the only person I've ever even heard of
who used a noncontiguous netmask other than for testing - for some
years my house netmask was 255.255.255.216, I think it was).
Maybe the prevalence of LPM hardware in high-end routers?
Maybe the politics of routing protocol design leading to protocols with
mask-width values rather than mask values?
Maybe, as mentioned above, their unpopularity with users?
