I don't think that's true, see the issues list for a lot of discussion.
I'm most familiar with the shared_ptr bits and there were lots of issues
raised about the design, many of which Peter Dimov had an instant reply
to, since the design and implementation were mature and he had already
thought about most of it before work began on TR1.

Even so, Christopher was proposing adding user-defined ctors to
boost::array, which would be completely incompatible with
std::tr1::array and would make aggregate initialisation impossible.

I didn't mean to suggest that, although I do believe there has been a
consensus not to introduce needless incompatibilities between TR1
components and the Boost libraries that inspired them.
