the internet must be neutral and transparent and the DNS is on a 
first come first serve basis managed by TLD Manager. The principle 
is: TLD Managers need a tool that permits them to avoid confusing 
registrations. This means that only the first confusable registration 
is to be accepted, not the others. This is not a filtering, it is an 
extension of the definition of what is already registered. Up to now, 
already registered means the exact string, it should mean the 
confusable string.

This means that this belongs to the TLD Manager registrations terms, 
not to standardization.

RFC 5895 states "As unusual as this may be for a document concerning 
Internet protocols, it is necessary to describe this operation for 
implementors ... which conflates [] user-input operation into the 
protocol.". This is the case of the discussed option. IESG has denied 
RFC 5895 the standard track. This should be the same case here.
