gs 10 changed from default-export-all to default-hidden visibility, which breaks app-text/dvisvgmm, undoubtedly among many others.

I don't really think this is a bug per se. They intentionally dropped the symbols and they break ABI all the time which is why the subslot changed (and changes on every release) and it's how people noticed dvisgm broke immediately (bug 873961). I'd prefer it instead if we filed bugs for each of the issues and fixed them. They were private symbols.
