Unity and Unreal still have more brand recognition, I'm sure there are project managers and creative managers that hadn't heard of Godot yet (though that is diminishing, I'm sure). More importantly, there is institutionalized knowledge and established tooling in place at a lot of dev studios. The expertise in one engine takes at least a year or more to acquire before you can really make the engine purr. But it also affects the whole toolchain, not just the part inside the IDE -- assets created elsewhere (models, animations, audio) typically go through some massaging to be compatible in Unity or Unreal, or the particulars of the scene/project and this often done through some automation, that automation would likely have to be rewritten for a Godot workflow, or even if it didn't, that's certainly what a PM or other decision maker would anticipate. There's also the asset store full of plugins, or in-house developed plugins, which extend the engine and would also likely need at least some part of it rewritten or replaced.
