I think insert-file-contents _is_ the proper way of doing what you
want.  You can see many examples of its usage in Emacs Lisp packages
bundled with Emacs.

FWIW, I think most, if not all, things inhibited by
mm-insert-file-contents are either not needed or incorrect.

auto-mode-alist is not consulted by insert-file-contents, AFAIK.

Why? to protect from someone who overrides the default?

insert-file-contents does not evaluate file-local variables, AFAIK.

This decodes the file, which you do want.

See above.

This is a bug, IMO, at least in the general case: why should any code
like what you wanted to write be prevented from working on remote
files?

I don't think find-file-hook/hooks is relevant, as you don't invoke
find-file here.
