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.
