Earlier quoted context omitted.
I've never seen (noticed) an OV cert in real life, and no business I've ever been responsible for pushed for OV over DV. It was always EV or "huh?"
I think I've seen one or two, and only because I noticed them as a weird callout in a $LARGE_FINANCE_INSTITUTION infosec bingo sheet. Of course I had to check that they really were running with OV certs. Some of the outfits in that space will be heavily hit by the shortening certificate max-lifetimes, and I do hope that the insurance companies at some point also stop demanding a cert rotation before 90 days to expiry…
It's not like you have a lot of choices when certificates are only valid for 47 days in 2029!
