You seem to DTRT.  However, for me I got no such warnings.
I tried the following things on

(export HOME=3D$TEMP; cd; emacs -q) ...[1]

for Emacs 30.0.50 and 29.0.60 (built yesterday), and 28.2:

| (add-to-list 'package-archives
|              '("melpa-stable" . "https://stable.melpa.org/packages/")
|              t)
| (package-initialize)
| (package-refresh-contents)
`----

(package-install 'w3m) and (package-reinstall 'w3m) issue no
compile warning.
(require 'w3m-load) and `M-x w3m' go silently, either.

Strange.

[1] i.e., no .emacs, no .emacs-w3m, and no site init file.
