That which was mentioned: as part of the language standard, I, as an
application programmer, can rely on the library being available and
usable on all conformant implementations, without any setup for the
build system to reference the library, without any special troubles in
getting the library itself to compile, without having to wrestle any
legal department to get it to work, without having to beg any college
course administration to install it - in short, I can use it just as
easily as I can use vector and string now.
You may not think that is much added value. My experiences, both first-
and second-hand, tell me otherwise.

What, exactly, is the cost in the scenario you described? There is a
freely available reference implementation, so the additional effort for
the compiler company consists of including this implementation in the
distribution. And doing some additional testing, perhaps, but if the
existing implementation has a good test suite itself, that shouldn't be
too much work.
So yes, I think it is worth the cost.
I want to say more, but my brain's kinda foggy.
