As an aside, bank websites don't necessarily fall in-scope for PCI.

I worked for a small credit union, and we were beholden to our state auditors, FFIEC guidance, and the like -- but PCI simply wasn't a thing we worried about.

Interesting. I know far, far less about the regulatory side than the practical side. I gather it's focused mainly on merchants, but the card providers themselves founded it?

I'm not sure what I can say except not every bank seems to share that view (although as said in other comments, quite a few banks do indeed have paleolithic systems in unexpected places, and that tends to extend to their security practices - I am not able to name any names, but I can wave in the vague general direction of things which involve VAXen, COBOL and DES-and-I-don't-mean-3DES, all of which thankfully predate me). But I'm not exactly familiar with US banking practices (thankfully): did the credit union just not issue any Visa/Mastercard/etc cards? Huh.

True, but this is because a large number of credit unions don't issue Visa / Mastercard credit cards directly; typically they do it through their banking partners (who are registered as banks as opposed to credit unions who for almost all cases are not banks), if they do it at all.
