The thing about coastal areas is they’ll always be a part of Earth’s biosphere. Unlike plains or deserts or deciduous forests, which don’t have to exist, and can completely disappear, coastlines and estuaries can only move, never disappear.
A coastline absolutely can vanish(submerged) or be against geography, such as rocky cliffs, that is unsuitable. “Coastlines can’t stop existing, only move” is semantic nonesense.
This is a cool point. I’ve never thought about that before. It’s a very stable environment allowing for efficiency to be selected for in ways that may decrease adaptability.

If a coastline submerges a new coastline is created further inland. ie, it moved. Or are you proposing a situation where all land is submerged?
You’re right, a beach can be replaced by cliffs that a crocodile wouldn’t be able to make use of. That’s a good point.
