I think that concept is very good for the defensive side, that's way I think china should use it in it's system of systems, also can be use as a sponge for enemy strikes. and you can use it as the attacking side by basing your forces on islands you can control in the fight.
But I should say that US can use it in islands that belongs to Japan, South Korea, Philippines and they can put some stocks their with minimal personnel, and then they can transfer personnel from islands to island to improve the manpower in that island, but most of the time they use minimal manpower that stays their.
I think it's a very good model in that sense, and I don't take the idea of just going in that island to make a one off salvo then leaving to fire from another island. But if that's what the US thinks, then that's maybe their way to make sure this states - Japan, ROK, Philippines - join the war and be the next Ukraine.
