THey have been suggested may reasons why some companies may not want to trust
and support IDN (IDNA + all other utf8 based proposals) in their applications. 
IDN  introduce ambiguity in higer layers than machine protocols.

By "trust" i mean that 7bit applications accept 7bit ASCII domains as fairly 
"unambiguous" identifiers historically and had been putting trust in it ..
I didn't mean soome trust mechanisms like DNSSEC or X509. Just common trust in ASCII
which is  the greast common divisor in all internationally-used scripts.

IDNA strings does not deserve the same trust as ASCII domains have now in end 
users.
