I expected this answer, but how about IGNORING that stricture for the moment and dealing with the conceptual implications of this level of hierarchy?

There are a zillion ways to transliterate (source script, target script), and I want to avoid adding a zillion new special subtags for handling this if it should be handled in terms of hierarchy.

Perhaps it is a good idea to consider revising it.
