The question is only if devices should be programmed in order to know
the future and it's potential proposed stadards by the IETF. Mind you I
don't know if the devices in question (websites, routers etc. droping ECN
packets) *are* violating a standard that was current at *their* time. The
routers in particular I think *are* wrong, since they are making decisions
based on bits that at that time were reserved.

But tell me, in case there's an IMAP client that has some problems with
the IMAP protocol. Should a Debian box by default *refuse* to talk
to it or should the default be to try to talk to it (provided that it
can)?

With ECN set, Debian's default is to plain *refuse* to talk to all
equipment which, for whatever reason has problems with ECN.
