defvar, defun, defadvice, define-minor-mode

[grolongo]

Hi, for a long time I put all my (defun... under the :preface macro. Never had an issue so far.

Now I found there are :functions and :defines macros.

Should I set everything like this?:

all (defvar... under :defines all (defun... under :functions

But what about defadvice and define-minor-mode? Those works if I add them either in :preface or :config, but I'm looking for the use-package conventional way.
