For those like me that work in industrial environments, when you need to
give support for 30 years, C++11 won't be an option in several years.
Not to mention safety-related qualified toolchains which are really
conservative. Silicon Valley is not the place were most C++ programmers
work. The only thing we really miss is move semantics, we can live
without lambdas, uniform initialization, etc. custom libraries can fill
missing c++11 std library features.

In any case Artyom, I designed boost.unique_ptr's C++03 mode to be as
lightweight as possible. Please take a look at it, it might work for you
as a long-term solution. Boost.Container also supports emulated move
semantics and boost.unique_ptr, so you might have a good ecosystem to
obtain more safety in C++03 compilers in a forward-compatible way.
