I agree.  I think there's a larger principle at play here: that a spec
should be usable by people other than the ones who were involved in
writing it.  That means that when there's useful context, it should be
included.  That's what the non-normative stuff is about, I presume.  And
a non-normative appendix on recommended practices and the reasons
they're recommended would be extremely useful.

Agreed.
