> This patch fixes an incorrect behavior of eglot. To reproduce:
> - run M-x eglot
> - run M-x eglot (again)
> - eglot now prompts whether to reconnect to the existing LSP
> - enter "n" (for no)
> - now eglot shuts down the LSP process and reconnects - this is not
> correct, the expected behavior is to not reconnect
> 
> The patch is below.

João, any comments?
