>> So... it may be reasonable to assume that any KREALM client could work with multiple realms, because they will normally be KDCs.  And that'd mean we wouldn't need this priority or go-for-this-one flag.  Agreed?

The referral that the KDC returns is one for which it succeeded to construct a TGT.  Having multiple realms gives an opportunity to try multiple paths in constructing that TGT.  I wouldn't be surprised if there are use cases that want to exploit this, even if it puts a strain on the client's KDC.
