The attack into an empty cell exploit still exists with attack ("a").
For example, in the standard game cruise around the ocean, trying to
attack random sea cells.  One will eventually find a submarine.

I haven't generally thought it is a particularly big deal, just
because the AI doesn't know to exploit it and a human player won't
have the patience to exploit it all that often.  But it would be nice
to plug, if doing so doesn't cause other problems.
