Do you think the same could be done for LSP definitions and implementations?

[tjdevries]

This is a good idea -- I think maybe we should do this as well for definitions and implementations. Do you want to do that or would you prefer if I did that in a separate PR?

@tjdevries It would be great I think if you could proceed with it 👍.

perhaps this should be extended to other lsp functionality as well e.g. lsp_document_symbols ?

Yes, also that, preventing any duplicate.
