What statement ? Boost doesn't officially support C++03, even if individual libraries still support C++03, so a PR that changes a library that currently supports C++03 as its base level to instead support C++11 as its base level by using C++11 standard libraries in its code instead of the Boost equivalent libraries, would not be a radical change.
That depends on whether or not the user code depends on the boost types which, as you know, work fine when compiled with a new C++ compiler. Supporting old compilers is only part of the motivation, the other part is supporting old user code; and it's safe to assume that for the user switching from boost types to std types is very difficult.
