Sounds right. All of these above is a much more useful statement to
make to users.

If an upstream dependency only works in C++11 and above, and the
library maintainer wants to support C++03, they can either:
A) Drop the dependency and still support C++03
B) Drop C++03 support
But again it will be up to that library maintainer.

You will be able to start using C++11 in the libraries that you
maintain, without fear. You won't be able to force another library
maintainer to let you use C++11 unconditionally in their library if
they want to support C++03 users.
