Ok, thanks for pointing this out - looks as if we missed this addition when we upgraded our system from the older versions we had supported previously. > The very old fee-0.8 version specifies in > https://tools.ietf.org/html/draft-brown-epp-fees-05#section-4 "Servers MUST > provide clear documentation to clients about the circumstances in which this > extension must be used.", which provides flexibility for the server to > normalize the behavior as defined in draft-ietf-regext-epp-fees-05, > draft-ietf-regext-epp-fees-08, and RFC 8748. Sure, it provides flexibility, but a registry must still be wary about the implications of any change in server behavior, even if the previous behavior resulted from a wrong implementation. We'll need to take this into consideration when altering the check results of our system where legacy versions of the extension are used. Our fee-1.0 implementation will for sure adhere to the language in the RFC. By the way, you're right that fee-0.8 is very old, however you'd be surprised that, for many registries, it is still the latest version they will support, with some only supporting even *older* versions (like fee-0.5 in the case of CentralNic). This has led to the unpleasant situation that some bigger registrars who want to avoid the effort of implementing newer versions even put pressure on registries to introduce support for these older versions, as they regard them as the established "de-facto" standard. Based on this experience, I'm afraid it will take a long time until fee-1.0 will be widely adopted by registries or registrars, if ever.
