I think it was over this debacle, definitely over some debacle, someone made a great blog post that pointed out this wording is usually incorrect (edit: Link https://blog.yossarian.net/2021/02/28/Weird-architectures-we... HN Thread: https://news.ycombinator.com/item?id=26294397).
It previously worked, but no one was promising support for niche architectures. It just happened to work (at least enough that there weren't obvious bugs, who knows if fully). Expecting support for every non-standard way you can use the software is usually not a reasonable expectation of maintainers.
