My current line of thinking is that they should not, as even Frank is having 
second thoughts about it. But I haven't made up my mind yet. There's not 
much time left though.

Not really. I just think that you're currently contributing in the wrong 
area. We need to flesh out the specifications of the changes we are 
proposing. And with regards to the implementation, you could for example 
contrubute boost/make_shared.hpp (including documentation and tests), which 
is already accepted and (I hope) stable and really needs to be in 1.36.

Yes, that's true. I view this as a separate proposal though since tying two 
more or less independent changes together increases the likelihood of both 
being rejected.
