Explicit call to package-initialize does not trigger a warn.

[Ergus]

Hi:

I have observed that doing an explicit call to package-initialize in the
init file is not triggering a warning as the documentation says it
should do in emacs 27.

The warning is showed (looking in packages.el) when package--initialize
is non-nil.

So I was checking the environment and package--initialize is nil at the end
of the startup if (package-initialize) is not explicitly in my init
file; but the packages are actually initialized.

Calling package-initialize (interactively or in the init file) properly
sets the variable. 

Maybe the issue is related with the fact that startup.el calls
(package-activate-all) instead of (package-initialize)

(and user-init-file
    package-enable-at-startup
    (...)
    (package-activate-all))

and (package-activate-all) doesn't touch the variable package--initialize.

Any idea?
