I will try to put it in another way, it's not only the native registry support, is more about the components that you put in there.
e.g. maven central is the registry and you put spring boot components in it so people can reuse them and not build the same things again from scratch.
I have the feeling now we all build the same components with pulumi and there is no reuse and sharing over a component registry.
does it make more sense now?
