I read this as "browsers do not want to update their code to work with Stix
1.0"
No, MathJax asks for 1.0, and fontconfig gives it 1.1, which is incompatible. If MathJax had asked for *any* version, then it would be a bug in MathJax, but it didn't.
Well, this is a browser bug. Upstream stix changed to take into account issues reported after their .0 release, it fixed actual correctness bugs and problems indentified in big apps such as office suites, it took it months of work and there's not way upstream is going back now
Upstream does not ship these aliases. If you look at the release notes, you see that several glyphs have changed locations, making these fonts incompatible. The aliases are purely a Fedora thing.
