Some people feel this, and well, if the KDC has better knowledge, it
could share this with the client.

It's not used from the KDC, if that's what you mean. The reason for
this is that we don't want any dependencies in the KDC on (possibly
very slow, and insecure) DNS servers.
I suppose your problem is that you have one DNS domain, with hosts all
living in different realms? If all your windows machines live in a
separate domain, you can direct that whole domain to another realm.
One other possibility is to generate the [domain_realm] from DNS.

This can only work if your clients ask for host/test_w2kserver@REALM
(incomplete domain), or if there's something wrong in your bind setup.
