> When `eglot-autoshutdown` is set, killing eglot buffers fails with a
> track-changes assertion because, from what I can tell,
> `eglot--signal-textDocument/didChange` is called when
> `eglot--track-changes` is `nil`.
> 
> Backtrace:
> 
>   cl--assertion-failed((memq id track-changes--trackers))
>   track-changes-fetch(nil #<subr F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_136>)
>   eglot--track-changes-fetch(nil)
>   eglot--signal-textDocument/didChange()
>   eglot--request(#<eglot-lsp-server eglot-lsp-server-10d3578e408f> :shutdown nil :timeout 1.5)
>   eglot-shutdown(#<eglot-lsp-server eglot-lsp-server-10d3578e408f>)
>   eglot--managed-mode(-1)
>   eglot--managed-mode-off()
>   kill-current-buffer()
>   funcall-interactively(kill-current-buffer)
>   command-execute(kill-current-buffer)
> 
> Reproduction:
> 
> 1. Start emacs with `emacs -Q`.
> 2. Run `M-: (setopt eglot-autoshutdown t) RET`
> 3. Open any file you have an LSP server for and run `M-x eglot RET`.
> 4. Kill the buffer.

Thanks, I added Stefan and João to the discussion.
