You don't really want paths like "locale/de-*-1901". You want concrete paths here and "*" has no business in a path. Ideally you would reference the "Language-Tag" production in BCP 47 (RFC 5646). However, since it is a large production and you don't probably want to directly incorporate it, you could incorporate the "obs-language-tag" production in the same document instead. You should still say that language tags used in paths "must" be valid language tags according to the more formal production.

Valid point. I don't think anyone will complain if we change this.

This is true... however, most engines implemented the case sensitive
requirement (implementers had concerns about Unicode case
comparisons)). I think it might be hard to fix this one without
breaking a bunch of runtimes and maybe content.... need to think about
it.

Search for "case-sensitively" or "case-sensitive" instead. The
case-sensitive requirement on files comes a fair bit.
