Good trick. Unless a truly lousy glue is used, a glued butt joint is 
already stronger than the wood. Tongue and groove joints would sure be nice 
for accurate alignment of planks very near the finished thickness to 
minimize planing after glue-up though. But that's a benefit for the shop 
that glues up the panel, rather than for the shop turning the panel into a 
soundboard - should they be different shops. With a reasonable degree of 
care (very possibly defined by exceeding the limit one time), panels can be 
safely handled without breaking them.

Incidentally, that cracked bass corner can be glued back together with 
little trouble and no discernable performance penalty. Just refrain from 
pointing it out to everyone who happens by, and no one will know the 
difference.
