It sounds like you are trying to shy away from making any changes in C and making a Lua only solution? If so, I don't think the read-only aspect for vimscript will be that hard.

With the recent lsp handler rewrite in mind, I am working on a plugin for razor (c# web) by re-implementing the logic from the Vscode extension. The way it works is by generating virtual docs with the c# and html in it, then attaching appropriate LSPs to those virtual buffers.

Then the 'main' LSP maps ranges, makes sub requests, and maps the result ranges.

Is there a place that I can hook just the lsp request/response so that if people have individual display over rides I don't overwrite them?

               ``` local req = client.request
                client.request = function(method, params, handler, tbufnr)
                    if wrapper_func[method] then
                        return req(method, params, wrapper_func[method], tbufnr)
                    end
                    return req(method, params, handler, tbufnr)
                end```

               local req = client.request
                client.request = function(method, params, handler, tbufnr)
                    if wrapper_func[method] then
                        return req(method, params, wrapper_func[method], tbufnr)
                    end
                    return req(method, params, handler, tbufnr)
                end```

do you mean something like this?

Or overwrite the existing vim.lsp.buf func
