FYI: I made that comment at the point of writing a parser to handle 
methods.

Having just read may way through 2 WebDAV and 2 HTTP RFC and re-read 
the HTTPbis drafts, your post came as a bit of a non-surprise to find 
there were more RFCs which I now have to read just to find out if the 
methods listed are idempotent and/or cacheable.

Having a quick reference safe=yes/no, idempotent=yes/no would greatly 
assist writing parser that treated these methods as safe or idempotent 
without having to read/support every RFC on the block.

An indication of cacheability would also be great, yes/no/conditional 
kind of thing. Something to indicate if we proxy authors actually have 
to read the RFCs in question for correct interoperable behaviour when 
handling the method. Otherwise the method is going to get left on the 
"other" pile and not be supported fro a longer time. Which is a shame 
for new cacheable method responses.


Just the core considerations requested for new methods. Since those are 
the details we have already as a WG identified as important/critical for 
HTTP software implementing the method to be aware of.
