And it doesn't in Firefox. If nobody tried to guess, if everybody
rendered it as instructed, then the person who posted the document
would have immediately realized the mistake -- and fixed it. Instead
we have random brokenness.

Just like with Joel's assumption that a non-RFC1918 IP address means
global reachability.

No, but I've changed a power steering pump. Mostly, I take the car in
for service and ask the technician to explain his recommendations.
Unless something raises a red flag for me, I then follow the
recommendation because those are the guys who know.

Which is also relevant here - RIRs like ARIN are the centers of
knowledge for operational addressing needs. While the IETF is
certainly the right organization to work out the technical details of
a shared address space, the protocol level musts and must nots,
they're a poor choice of organization to determine -whether- there's
an operational need for an address space with 2011-5's parameters or
-how much- address space should be dedicated to it. They don't draw
those experts. We do.
