I think I would go with Lithium technology for a bi-polar battery or installer disorder, ask your doctor or psychiatric health provider ;-)
I am chalking this up to old-time off-grid lore I've never heard of before. and I'm an old-timer at off-grid too. The way to protect those string end batteries from problems is the same as every other battery in the series/parallel bank -- regular maintenance to maintain clean low-resistance connections, but especially on the main corner DC connections to the inverter / power panel etc. Perhaps a case of "it ain't broke, don't fix it, been workin' fine all these years?" .
