(You are right of course. With the data we have now, we are quite certain that Omicron is much milder. Hopefully no lockdown is needed.)
But, personally, I would like to avoid getting Omicron, as long term effects are still unclear: does "long Omicron" exist, does it affect vaccinated, and if yes how common and severe is it. There are some recent news about long Covid: it could be micro-clots.
