I)
There are files with more than 1 maintainer/author.  Just pick up the first one
may not suffice.
E.g.,
(lm-authors (find-library-name "tramp"))
=> (("Kai Großjohann" . "kai.grossjohann@gmx.net")
    ("Michael Albinus" . "michael.albinus@gmx.de"))

(lm-maintainer (find-library-name "tramp"))
=> ("Kai Großjohann" . "kai.grossjohann@gmx.net")
;; Your patch won't send CC to Michael.
I suggest to CC all of them.  In order to do that `lm-maintainer' must
be updated.  See patches below.

II) There are files with plural versions of 'Author', 'Maintainer' headers
For instance,
lisp/net/rcirc.el
In this case `lm-maintainer' fall back in `lm-authors' so that Liu wouldn't
be in CC.

Another example,
lisp/color.el
Just 'Authors' header, no 'Maintainer' one.  There wouldn't be CC in this case.

III)
The e-mail format might confuse these tools.
E.g.
lisp/org/org-protocol.el
;; Maintainer: Sebastian Rose <sebastian_rose AT gmx DOT de>
or in
lisp/progmodes/prolog.el
;; Maintainer: Stefan Bruda <stefan(at)bruda(dot)ca>
