Pozidriv is intentionally not backwards compatible, and one of the biggest problems it has is looking enough like Phillips that people assume it must be compatible, use a mismatched screw and driver, and strip a head.
Which is why it sucks. I go to work and I see a cross cut, I’m going to use my Phillips head of appropriate size to pull it out or put it in. Does pozidrive have any indication it’s not Phillips? I’ve honestly never seen one. I might be working on brand new stuff or 60 year old stuff.
I don’t have any pozidrive bits but I have two sets of long torx, some double sided torx for my hand driver, and a bunch of little torx bits in my bag to hand out to the kid that came to his first day of work with nothing but a #2 Phillips.
I think it’s pretty likely that you’ve seen loads and never known they were different. The difference is small enough that you wouldn’t realise it was significant until you were told:

Yes, the head is visually distinctive from Phillips, with four smaller cuts in between the main ones.
Good to know if I ever see one.
