Yeah, this has been mentioned before. People basically suggested turning DCC
into TFTP (using an ACK and an ORD type system). However, that seems rather
stupid to me. Then you're basically turning UDP into TCP, so why not just
use TCP?

I don't think anyone really ever decided on why UDP was needed though...
