I have done some very preliminary experiments with this idea some time
ago; I made a version of unbound that sent TC=1 to every UDP query, and
only actually answered TCP queries.

Unfortunately the first few machines I tried it with didn't appear to
retry over TCP, so I didn't pursue further at that time. Might be
willing to have another look at it if there's more people interested.
