Probably so, but then how bad would blistering have to get before it

that were easily the size of softballs, eating well into the hull

There are no recorded cases of sinkings or structural failure caused
by osmosis. OTOH it is unlikely that any sensible person would put to
sea in a seriously damaged hull to tempt such an event.

In general the repair of small osmosis blisters has more to do with
maintaining resale value than with safety.
