Yes... for every new project or actively developed one C++11 is great.

But there are two areas where it isn't

(a) Existing projects that need to be maintained in new environment
(b) Libraries that need to support C++03 as they are used in wide range
    of environments (like Boost for example) and should provide
    same API.

Yes... but that is why if you want your code to work in Kernel you
should push it to kernel and not keep to yourself. Kernel API
is internal API of project.

On the other hand user level API (i.e. system calls) are almost NEVER

I suggest if you refer to Linus and breaking API take a look on Red Hat
and memcpy... when glibc decided to reverse copy direction and Flash
stopped working. Linus was very critical of breaking stuff in User space.

auto_ptr is user space. It isn't internal implementation of things
it is public API and for kernel it never breaks.

It is really frustrating the ease the API breaks effecting entire
