In RFC 2119 (the document that defines MUST, SHOULD, etc.), "MUST" does not
mean "vitally important" and "SHOULD" does not mean "really really important,
but less important than MUST". "MUST" means "you have to do this or you're
not going to interoperate." "SHOULD" means, "there are ways to not do this
which will still interoperate, but you had better know what those ways are
and you better be sure to do them, and if you don't, then you MUST NOT do
this." That is, "SHOULD" is equivalent to "MUST unless you know exactly what
you are doing."
Sounds like we SHOULD all go back and re-read RFC 2119.
