No, I absolutely do not do this. For one, I don't have any network requests in my vimrc. I also keep my plugins versioned using an external tool that pulls them from a given git hash rather than request them from some other server.
Well then there is Emacs which is like an entire ripscrip BBS in your terminal if you configure it that way. If the Lisp you hand edit to actually make the plugin start up works you may want to also see what it’s doing apparently. Even though that happens sometimes Emacs is very good at what it does.
