Seems like John is asking for
3) ACE labels obtained from domain name slots SHOULD be hidden from
users when it is known that the environment can handle the non-ACE form, except
when the ACE form is explicitly requested.

When it is not known whether the environment can handle the non-ACE form, 
the application MAY use the non-ACE form (which
might fail e.g. by not being displayed propertly) or it MAY instead use the
ACE  form (which will look unintelligle to the user).

I think something like the above text is better than what is in the document.
