My argument has been, "The Java generics spec is already complex so why give
an API three type parameters and two wildcards if it only needs two type
parameters and one wildcard?"

This way, if you know that the output from Iterables.filter() is an
Iterable<Number>, you know that the input was also an Iterable<Number>, and
vice versa.  There aren't unnecessary degrees of freedom.  I'm actually
really surprised this could have made your type inference *more* difficult.
