No.  An unintended short in the drawing is not a DRC violation.  Testing
the connectivity is not DRC.  A DRC check is independent of the desired
connectivity. DRC checks if the manufacturer can reliably implement the
layout with the same connectivity as drawn.  Flagging zero clearance of
a pad as a DRC error is wrong, even if the connection is undesired.

I personally prefer if the DRC check tool does pure DRC checks and not mix in
connectivity checks.  You may well disagree.
