Thats exactly it - deep water is impassable so building on the coast means you never have to worry about raider attacks from one direction (hell there are a few seeds which have coast on three sides so you always know where the raids will come from) this simplifies defence designs a lot - in addition shallow water slows movement massively making it very helpful in slowing assaults.

Once you master funnelling the enemies the only types of attack that can hurt you are Drop pods, Space ship crashes and Sieges (add in infestations if you build into a mountain).

some of my late colonies dont even require colonists to defend - the traps plus turrets just decimate even large tribal hordes... it makes the game a little more dull and predictable which is counter to what makes the early game so fun (you are always one bad event from failure).
