Paul,
I suppose that if your tank fills with water, you will looses some buoyancy. 
I've never heard of that happening to that extent, though.

A little water usually  enters a scuba tank when it is totally empty and the 
diver descends deeper before surfacing.  This can happen after breathing a tank 
dry, then descending, or by descending after a malfunction.  If someone is in a 
cave or wreck, and must descend before ascending, water could enter an empty 
tank.

When I was a kid, I breathed a tank dry, and then continued to descend.  Water 
got into the tank, and rusted it beyond repair.  I didn't have the "excuse" of 
an overhead environment to blame for that one; just bad judgment due to being a 
kid.

I agree that a diver SHOULD be able to reach your valves. Try as I might, I 
simply can not reach mine when dressed in a drysuit with heavy underwear.  I 
need to loosen my harness and move the tank a little towards my head before I 
can reach them.

I once saw a rig where a ripcord type line was wrapped around an isolator valve,
and clipped to the harness near the shoulder.  One quick jerk on the ripcord, 
and the isolator valve closed.  Of course, that's one more line to get tangled!

There's another factor I haven't seen mentioned yet. If a tank completely 
floods, you can lose a lot of bouyancy, can be quite serious if the 
     bottom is far below.
