If you don’t use anything from the engine itself, implement everything from scratch, only using the engine as an entry point that launches your own code, and pay unity two thousand dollars per year per seat for that privilege - I guess porting should be fairly easy.
If you ask me engines should be free for most indies (UE, Godot?), because they’re not making millions.
But yeah. I get it’s not feasible for most new devs especially, and senior devs have better things to focus on.
The surface area is huge. This is not an SQL database where you can just change the ORM’s backend.
Depends how it’s built.

It’s more a code principle you’d stand behind.
