I agree with you that making these symbols STB_LOCAL is a bad idea.
In fact, I considered that to be the bug and was planning to fix it

If you could help me with info, please: What is this "ABI draft"
mentioned in the comment, where is it, and who's working on it?

Well, then, does libstdc++-v3 needs to check something more than gas
support before it uses '.hidden'?
