Speaking only for myself, I didn't say that.  I said that printers and 
print drivers that follow the remove-from-right algorithm described in 
RFC 2911, trying to match their input against an internal language-only 
tag, would be unharmed if the input changed from language-region to 
language-script-region.  And I said that our priorities for assigning 
Suppress-Script values should be directed toward languages for which 
regional variants are thought to be worth tagging, and thus most likely 
to exist.

Of course, now that IPP has been shown to implement an incomplete, 
simplified model of RFC 1766, rather than RFC 1766 itself, and that both 
RFC 1766 registered tags ("i-default") and RFC 3066 built-in tags 
("fil") break this model, we can't really expect it to work perfectly 
with RFC 3066bis either.  All we can do is add the Suppress-Script 
values we can agree upon conclusively.

Based on this discussion, though, I've seen the light and changed my 
tag-generating utility so it does NOT generate Suppress-Script-violating 
tags by default -- only if the user turns off an option that is 
initially on.
