The reference you mention in 610C was not intended as an encouragement to use unsupported solder as a method of modifying circuit operations. The statement actually began life as something like " an path between electrically non common conductors". In committee discussion there were cases illustrated to the effect that it could be intentional and if it was then there should not be a mandatary reaction by the standard definition. Additional definition is provided in J-STD-001C in paragraph 9.2.4.2, f "Solder bridging between joints except when path is present by design" which is pretty much the same as 610C. I do not currently have access to reliability test data, although the tests have been conducted and there should be information available from one of the TNers.
