No problem.  I did the same thing with 2616 (Apache httpd
implemented 2068 and then I was way too busy trying to get
my dissertation done to pay attention to 2616, sadly).
HTTP has gone through several waves of expansion, as various
experiments were deployed, and then contraction as we figured
out which ones didn't work in practice.

Great.  Is there any chance that you have a list of features
or requirements that you did not implement (on purpose)?

I don't have much opinion on the proposed timeout features,
but I do wish that folks would pick shorter names and make
use of the existing ones (like the options on keep-alive).
