Maybe it's analoguous to the old adage "what intel giveth microsoft taketh away". As soon as a critical mass has SSDs, no one cares to test regressions with spinning disk systems...
Actually, bad I/O patterns are still bad with SSDs. They're just less bad. So, while a HDD user maybe has to wait a week for your app to do its thing, the SSD user may only need to wait an hour or two. But if you bothered to do things the right way, either could be done in a few minutes.
One of the large World of Tanks (online game) patches last year turned 10 second map load times into full minute wait for HDD owners ;-) SSD users didnt notice a thing. Some idiot with dev workstation (xeon, high xx GB ram, NVMe storage) decided to rearrange data structures in files loaded every game round, and nobody has time for testing apparently.
