That's not what RFC 1035 says at all. "When data enters the domain 
system, its original case should be preserved whenever possible." 
With IDNRA, the data that enters the domain system has already been 
changed.

Correct. It is destroyed on purpose, just as it is destroyed just 
before comparison in today's DNS and then restored after comparison. 
However, this doesn't change RFC 1035. The data entering the domain 
system is not changed by IDNRA.
