It's in doc/lispref/tips.texi:

    @section Emacs Lisp Coding Conventions
    
    @cindex coding conventions in Emacs Lisp
      Here are conventions that you should follow when writing Emacs Lisp
    code intended for widespread use:
    
    @itemize @bullet
    @item
    Simply loading a package should not change Emacs's editing behavior.
    Include a command or commands to enable and disable the feature,
    or to invoke it.
    
    This convention is mandatory for any file that includes custom
    definitions.  If fixing such a file to follow this convention requires
    an incompatible change, go ahead and make the incompatible change;
    don't postpone it.
