Yes, this was my initial hope too, that something like
`pp-macroexpand-last-sexp` could help me.  But it's got
enough fluff to make it tiring to read.  Here's what a simple
'(use-package foo)' with no options expands to:

(progn
  (defvar use-package--warning1
    #'(lambda
        (keyword err)
        (let
            ((msg
              (format "%s/%s: %s" 'foo keyword
                      (error-message-string err))))
          (display-warning 'use-package msg :error))))
  (condition-case-unless-debug err
      (if
          (not
           (require 'foo nil t))
          (display-warning 'use-package
                           (format "Cannot load %s" 'foo)
                           :error))
    (error
     (funcall use-package--warning1 :catch err))))

I'm afraid mode options will make this even more
complicated.  And what's with that defvar?
