I've seen (non gaming) frameworks live or die by how well they work turnkey, out of the box with zero config edits other than the absolute bare minimum to function. Even if configuration literally takes like half an hour or something and the framework has huge performance gains over another, that first impression is a massive turn off to many.
It's... not that people are lazy, but they're human. Attention is finite. If realistic lighting isn't good in Godot by default, then it needs a big red intro button that says "Click here for realistic lighting!"
