No, not at all.

First, the discussion above is not talking about BEAM tech at all.

Secondly the environmental requirments for the robots being compared are
exactly the same, its a trial of different behavior sets being tested in
a known environment.

Thats where the second set of trials enters the picture. Once you have
a standard way to testing behavior sets, its a simple matter to test a
modified or new body against the 'standard' design.

Why?

You can still innovate new designs, but now you have a way to directly
test
to see how much improvement (if any) your modifications made?
