There are many. SAML 1.1 is unable to support the technical approaches I 
chose, and I have no plans to address that. Lacking a proper subject 
confirmation schema, encryption support, limitations of the browser 
profiles, it's just not reasonable and I don't intend to try it.

It has no OASIS life cycle. I cannot emphasize this enough. This draft 
has nothing to do with OASIS or the SAML TC, it is a personal document 
submitted to the project I work on (thus the filename). I will be 
updating the document to reflect this.

So far, one small piece of it (profiling assertions) has produced some 
interest, and there's a knock-off of it circulating on the official TC 
list. I don't know whether there will be interest in advancing that. As 
for the rest, I have no idea, but I doubt it. The second half of it I 
expect to drop entirely, or morph into something more directly related 
to Liberty.

I'd note that there's nothing in this draft you can't already do with 
Liberty ID-WSF, and it supports other token types as well as SAML. The 
point of this document was partly to provoke comment in my community 
about whether something new is even needed.

I'll leave as an exercise for the reader to ask about the viability of 
"web services" if nobody can figure out how to do stuff this basic with 
all the specs out there. I think that's a telling problem.
