Directives vs JSX

[Pipe-Runner]

Hi, everyone. I have been writing my custom components for the editor. What I need help understanding is if I have JSX available, what is the point of having directives? Is there a case that JSX cannot cover?
I read one discussion which stated that a custom editor for JSX was unavailable, and the library author wished to enable such an editing experience for JSX as well. But I still need to find out the status of that feature. But if both JSX and Directives support CustomEditors, then I need to know which one to opt in for custom components.
