If a client is incapable of acting as an Ultrapeer, it can either continue to operate as a regular peer or connect to an Ultrapeer as a Leaf client.

This is why (in LimeWire) you can disable Ultrapeer functionality, and the user will become a shielded leaf node.

Can you give me technical reasons why this is a bad thing?

I see... Ultrapeers are not completely seperating themselves from regular peers. AIUI, Ultrapeers are fully capable of connecting with regular peers.

Ultrapeers shield low bandwidth users from high amounts of traffic. When Ultrapeers are clustered together, the possible search horizon is increased.

I agree with Rapheal Manfredi (sorry if I spelled that wrong) that Moak, and users of both sides are not listening to eachother.
