It is absolutely still true, most ship engines are not removable without breaking the hull above the engine.

Seems to me, especially with electric engine pods, ships can be designed to allow the replacement of the engine/generator.

They can be, but the ones that are currently afloat haven't been.

Shipping companies have had decades of success fighting against legally-mandated retrofits - double-hulled tankers, trivial safety features for passenger ferries... I don't think your idea of replaceable engines is going to get any traction.
