That's neat, I like it. The alternative -- to specify multiple values
on 'text-transform' -- is clunkier:

   @text-transform german-lowercase { convert: "ẞ" to "ß" }
   text-transform: lowercase german-lowercase;

Why not just:

  @text-transform latin-only-uppercase { convert: "a-z" to "A-Z"; }

It's shorter and we don't need to introduce another descriptor. (Which
leaves us with only one descriptor, but that's ok)

Agreed, this looks good.

Yes, I think it should wait.
