Well if they have to be same, there's no concept of winning. The spec says
they (RFC2119) SHOULD be the same. In my experience, if you say two things
have to be the same, they never will be.

Um, no offence, but backwards compatability be damned. This thing has only
existed for 2 weeks and the number of blogs implementing this can be
counted on the tips of our fingers. :-)
Let's get it right straight away. I see no advantage to making HTTP header
parsing optional. I just added support for it to my blog and it took all
of one line of code. I really wish we didn't have to consider bookmarklet
implementations, actually, since they are the only reason that the MUST is
qualified by an "if possible".
