well other than if (when?) it's endemic, and whether that could've been prevented, or if a new mutation based on omicron becomes deadly
if I was a virus I would probably want to be omicron, extremely easy to replicate and perpetuate your existence, and you're not deadly which also keeps you circulating, and the humans stop trying to even stop you
just not a fan of going from expecting to get a cold and a flu once a year, to expecting to get a cold, a flu, and covid omicron every year
