Not really.  There is support here for using unittest.main() whereever it fits and cleans-up the code.  That is not the same as saying we can eliminate support.run_unittest().  That is likely a more thorny issue and may affect users outside the standard library.

Because we don't backport this sort of change.  The ship for version 3.4 has sailed.  There's no point in rewriting history for something that isn't a bug fix, documentation fix, or performance regression.  Also, who knows who is already relying on the current setup and would have their code broken in the next micro-release.   (Second law of time travel: the past is infinitely fragile and the future is infinitely mallable)
