I’m not sure that’s trivial.  Would all of the next layers enforce them?  (Blogspot.com for example, I have no clue what, if anything, blogspot does for IDN, but it’s a place that allows random users to create domain names).  How would we know?

Some of the registrars also originally stated that they didn’t want to bundle.
