I did a little research on that:
The '-T' option is passed to the whois server, it's not a client option.
Intelligent or modern clients know what options to pass to the appropriate
server, in this case '-T dn' to the DENIC whois server.
This option is completely legal and was introduced at DENIC in an attempt
to better protect the domain holder's privacy (you know, different
country, different rules). This was many years ago, but it's still there.
RFC 3912 doesn't specify what output the whois server is supposed to send.
Everybody "assumes" that it should be the complete domain information, but
that's simply not the case.
Imposing this assumption is what Mouse does, and that is wrong. Heck, I
could even have a whois server that tells me the current weather forecast
for a specific request ;-) It is a minimalistic directory service, nothing
