I believe these should all go together: the reason that we propagate all configured languages to the formatting library is to be able to use them as a replacement for the BasedOnStyle in RawStringFormat. To make this possible, we need to update the internal structure of RawStringFormat itself to base it around each language. The canonical delimiter part is just a convenience for this I guess, which could be split.

My biggest concern with (1) is that since it has no visible behavior and no other uses except for the adaptation of (2), it is not testable by itself and it's not evident that a patch doing just (1) would handle the things correctly.
