I think both running a line and progressive penetration have their
place, and with good training and some experience, a diver will
learn to recognize which method is best suited to a particular
situation. The inside of a shipwreck is _very_ different from the
inside of a cave, and I don't believe that cave diving rules can
be blindly applied across the board to wreck diving. I don't think
wreck diving rules work across the board, either, as there is a lot
of variation in conditions depending on where you're diving and the
condition of the wreck.
That said, I've found small strobes (Trident has one that takes a single
"C" battery) to be useful in wreck penetration. They're not a substitute
for either guideline or progressive penetration, but they can serve as an
aid to navigation, clipped off at strategic points (doorways, openings,
corners) within the wreck to serve in a "backup brain" capacity in case
you do get away from your line and/or disoriented.

Yes.
