I agree with everything you've said, especially how LSP's simplicity has been key to its success. I do also agree with the author and would like a standard extensibility point, so that LSP could be the One True Way for every language to have full support in every IDE. I just want that to be done slowly and carefully, because it would be very easy to get wrong. If I had to guess, I'd say this might be coming in the future. Possibly Microsoft wanted to break out of its habit of overengineering things to encourage uptake and avoid scaring people away. They might be willing to carefully add more to "LSP 2.0" once people are comfortable with it.
