It reminds Postel's Law:

"Be conservative in what you do, be liberal in what you accept from others." 
[Section 2.10 - RFC 793]

So... if the RFC states that it should run over telnet, then standard
implementations should do it. But, according to Martin's proposed
rules -- which I entirely agree with -- my vote still doesn't count,
as I haven't reviewed any patch yet; so please take it only as a
general opinion on the subject.

low demand nonetheless. Priority may be low, but its still a relevant
patch, IMHO
