Godot is also behind the curve on content pipeline tools. I love it to death, but I would never be able to convince anyone outside hobbyists to use it because it has no goddamn FBX support, or an easy ECS framework.
Traditional ECS doesn't fit with Godot's philosophy, but you can make behaviors into nodes and just add these nodes as a child for ECS-like behavior. Honestly, I find Godot's way more natural and extendable.

The problem is that everyone is just sitting and using proprietary FBX format and don't work towards new open standards like Collada or GLTF2.
In all honesty (without knowing the specifics of what is broken, I've only ever worked on FBX importers), if Godot want to be taken seriously then they need to be able to import without plugins, warts and all.
And no, I am not talking about the Asset Library.
