No, because there are *std*::vector & co and there
are *interprocess*::vector & co and I've never heard
that there was an intention to replace the former
with the latter. However there *is* an intention to
replace (in my view extend) std::string.

IMO zero (as in 0) backward compatibility => zero (as in 0)
chance of adoption by the standard.
People (including me) who have proposed to just switch
to UTF-8 have met a lot of resistance, just because that would
break some things at run time. And I personally believe that
most (more than 50%) use-cases of string are encoding-agnostic
so it would not basically break anything.

If the standard commission somehow adopted the completely
different string you propose, that would totally *W*H*A*C*K*
pretty much all existing C++ code. std::string is not std::auto_ptr.

And IMHO this will happen only if you, besides the new
string, have also invented a mind-control death-ray :)

No, std::auto_ptr is/was nowhere near std::string when considering
the "frequency of usage".
