Ben, the idea is that this is a very targeted approach for SDNs, not something that makes sense as a general update to the DHCP base specifications.   Since relays and servers are generally within the same administrative domain, there is little danger of actual interop issues—the operator is going to be customizing these settings very deliberately.   We also tend to assume that the DHCP server is pretty easy to update compared to relays or clients, so the fact that an updated relay might not work with a non-updated server isn't a major issue.   This isn't like TLS 1.3 where the server and the middleboxes are operated by agencies unknown to each other.
