Their argument is the PCI council will mandate TLS 1.3 soon. This is not
the case. A TLS *1.1* mandate by the PCI council has been delayed until

I work for a company that directly participates in the PCI council, and
have been participating in the TLS and CFRG process for several years
(again, I do not directly represent either in this discussion).

I do not think that TLS 1.3 in its current form will cause them any
practical real-world problems for these companies, rather they seem to be
attempting to futureproof their current bad practices.
