It is a huge risk for aspiring console developers, to depend this much on a single individual (not trying to be ungrateful or underestimate the effort it took to write the code to port to Switch, just being realistic from a business point of view).
The process to port to console and the access to the code and libraries, once you are approved by Nintendo, needs to be more transparent and automatic as with other platforms, if Godot will ever be intended for serious and commercial game development beyond PC and mobile. The current situation is not sustainable. There has to be a better way.
For new developers reading this and considering to use Godot for console projects, I love Godot, but think twice, as of september 2021, the situation described in the post and comments has not changed, sadly. For the sake of the community and the success of Godot for commercial use, I hope it does.
