I know of valid implementations. I would like to have them in Boost.

Right.

Right.

I would like to reduce dependencies to Boost libraries as much as possible.

When the new feature can be implemented only if we have already an 
implementation of some parts of the standard library this needs 
evidently much more work. E.g. changing the constexpr of some member 
functions, ...

This is way I'm not interested on working on these features as part of 
Boost.StdExtensions. I'm interested in working on the new features that 
can be added on top of a C++11 version?

Boost.StdExtensions could be in someway similar to Boost.TR1. But I 
would like to reduce the dependencies to Boost.

Boost.StdExtensions would contain only features that have been approved 
in a C++ standard version but that are not delivered by the standard 
library associated to the compiler version.
