You can see that right now with TLS and the TLS working group, which still hasn't fixed MtE block ciphersuites because veteran implementors can't get it through their heads that MtE is a design flaw.
Can't get it through their heads that MtE is a design flaw? You're more generous than I would be. At this point I'd assume that everybody knows that MtE is a design flaw, and anyone designing a protocol which uses MtE has made a deliberate decision to design a weak protocol.
