It depends on what your circuit is.  IMHO in general grounding is
better than not grounding, but I've done plenty of slow-clock boards
with unconnected copper just to keep the etching happy.

Usually, by the time you need to worry about these issues, you know
the answer ;-)

BTW in PCB, such islands are automatically removed unless you
explicitly mark them to be kept.
