It’s about commercial contracts and NDAs and that sort of thing. You can’t share the console SDKs, so you can’t ship the features with the rest of the code due to contract reasons, so after your done, you share for a nominal fee (because contract/business reasons) the bindings between Godot and the console SDk, and then the studio who wants their game on console still has to get all the console SDk contract stuff done before they can actually build and test a console version.

I’ve looked into it with both Unreal, Unity, and a couple random engines that advertised their explicit support for various consoles… there is always some business contract stuff with the console owner company before you’ll ever be able to compile for the console, and then depending on the engine there is sometimes a deal you’ll have to cut with the company that built the console specific code/middleware/port/shim/adapter/etc … no game engine ships out of the box with a “build for XBox/Switch/PlayStation button” even in Unreal you’ll need the platform SDK installed and wired up which is documented from the Unreal side, but not provided, you have to get all the other half from the console vendor.
