Probably most people would agree.  However, I would want a very positive
way to disconnect the battery from a) the starter and b) whatever else might short.
Burning insulation in the cabin is seriously no fun.   We had a post recently of a guy
with a stuck starter contactor that couldn't get it to let go.   Your next line of defense would
be the main battery contactor itself in that situation.  For those two situations you want
a really high quality, high break current, contactor at the starter and main battery.  If it were me I wouldn't accept anything
less than a wr582 but actually I went with kilovac ev200s.
 
....but being a little imaginative with the other scenarios, suppose you somehow stressed one
of the biggish ring terminals on your grid or ground bus and that wire was just wondering around
looking for something to connect with.     Good workmanship is the best defense, but for that particular
situation, if you had the batteries in the back, wouldn't you want something near the front that would
take the battery out of the loop?  
 
It is really amazing how long a big battery can keep an electrical fire going if you can't get the thing off line.
 
My plan therefore is to make sure something else opens or fuses before the wire melts down.
