Re: Emacs as an Org LSP server

I'm afraid things still aren't clear for me.  Is there a reason it's so
hard to give a concrete example?

If I try to analogise from how LSP works for golang, I believe the LSP
server does things like
- complete symbol beginning with "Xyz"
- tell me where so-and-so function is defined (e.g. so that the client
editor can jump to it).
I'm not sure if operations like that make sense for Org.

Another possibility might be interacting, from a 3rd party editor, with a
body of Org content that has been primarily written and managed in Emacs.
If so, what would those interactions be?  Marking a task as done?
Something more complex than that?

Or is it like: 3rd party editor opens an Org file and the user types some
<random key sequence>.  Editor asks the LSP server (Emacs) "what does
<random key sequence> mean?", and the server replies "it means the Org
entry should now look like this: ..."
