I have dealt with banking environment when they required SSL with at least 1-year validity on the callback API URL. Which excluded Let's Encrypt.
We were looking for a SSL provider that had > 1 year old certs AND supported ACME... for some reason we ended up with SSL.com that did support ACME for longer lasting certs; however, there was some minor incompatibilities in how kubernetes cert-manager implemented ACME and how SSL.com implemented ACME; we ended up debugging SSL.com ACME protocol implementation.
Fun. We should have just clicked once per 3 years, better than debugging third parties APIs.
No, I don't remember the details and they are all lost in my old work emails.
(Nowadays I think zerossl.com also supports ACME for >1 year certs? but they did not back then. edit: no they still don't, it's just SSL.com I think)
