Not that I know of.

Because it affects how likely they are to be run with older versions
in my experience.  If they're in the source tree, it doesn't happen
(ie, people only run the tests that come with the particular version
of the source tree).  Backward compatibility is lost because they
diverge, and then nobody wants to expend a lot of effort making them
backward compatible when nobody will run them with old versions
anyway.
