This "name-something" functionality for import of 3D scenes is quite handy. https://docs.godotengine.org/en/stable/tutorials/assets_pipeline/importing_scenes.html
I don't know if shaders fall into this category, because everyone knows that it exists but I always feel like many people are afraid of trying to work with this and so just skip this entirely... And of course this is not limited to Godot.
Arguing about how one language is superior to another and the never ending tabs vs spaces discussion is a very important part of dev culture.
