I don't think this is a safe assumption to make -- for instance, DSLs tend to have operator overload return types that aren't necessarily the same as the class type.  Also, it's quite common for older code (pre C++11) to return void and make these functions private (with no definition) as an early form of deleting the operator.

How many additional diagnostics does this modification produce over some large code bases (particularly ones with DSLs if you can narrow the test field a bit)?
