That's something entirely different, though. Test to destruction/failure is done to check or verify the limits of a systems.

This test on the other hand was a test with a low change of complete success and thus failure was an expected and acceptable - but not the intended - outcome.

I take your point but if this flight had landed they would have probably kept test flying SN-8 until it did crash. There is really no other use for it.
