We have trained all users since the birth of the DNS to expect that 
"", "" and "FREENET.DE" all point to the same host.

I (speaking from my Norwegian context) think it's essential that the same 
thing be true for "Ålesund", "ÅLESUND" and "ålesund" too; that's the 
general "application" of "humans type a domain name and expect it to behave 
like domain names they're used to".
