That doesn’t mean it can’t be done in a new update! Lots of mods have been made into actual features, such as tech stacking and auto-explore. Not to mention the HD expansions from my understanding started in the minds of several modders. I personally feel like bridges are an important part to have with the other features. I’m sure a lot of people have seen these concepts and objects in the scenario editor and been disappointed that they’re not available in the scenario-based gameplay. I’d also like to bring up this post from 2022 about water in the game.
It highlights that there is a problem with naval features in the game and it is one aspect that causes a bit of a lull in gameplay.
