Um, no. That would break the performance of any number of applications
that don't need thread safety or have handled it properly themselves.

If you want a language where you can write anything and the system is
designed to account for every possible contingency, that's fine. But
that's not C++, nor is it going to be, nor should it become that. What
you want is a higher-level language.

And I'm pretty sure no language makes *everything* in its standard
library thread-safe.

This really feels like, "I got bit by a bug someone else put into
their code, so I'm going to assign responsibility for it to a third
party who now should help the second party make their code better."
Getting hit by bugs in other people's code isn't great, but this just
isn't a reasonable response to that.
