The diversity option is aimed to hop over the radio more costly.

It is well explained by MeshDynamics:

They also explain the problem (bandwidth, lowest bitrate link) of
hoping over the same channel:

I am gonna test the code this evening in an openvz simulator, and

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."
