Why would you want more?

For increased redundancy?  I'll tell you this - if any of the root
server maintainers have any smarts, they have probably put backup
copies of their name server(s) in multiple locations with some failover
mechanism, and with multiple physical servers doing failover at each
physical location (think F5's BigIP/3DNS).

And I think that some of the server maintainers may have some smarts.

Several have already mentioned the number of answers that one may fit
into a UDP packet without having to turn to TCP.
