I'm not well-versed in these issues, so apologies if this is misguided. Would the following work?
* Call package-initialize *before* loading init.el
* Add two new functions package-set-load-list and package-set-archives that call package-initialize after setting the relevant variables. This could be extended to any other variable that affect the behavior of package-initialize. If there are many, a larger package-configure function or macro might be more useful.
The hope it to settle this package.el trouble by providing something that works without requiring users to add a package-initialize form in their .emacs.
I can see the following downsides, and potential fixes:
* What about existing configurations? Presumably they currently call package-initialize, so this wouldn't break things for them.
* What if people set those variables directly and expect things to work? We could add watchpoints on these variables, or keep the package-initialize call that runs after loading init.el. I don't think people would expect setting a variable to do much, so I don't think thatwould be much of an issue.
* What about performance? Won't these extra (implicit) calls (from package-set-archives etc.) make things slow? We could make them reload only what's needed. IOW, package-set-archives would be akin to (progn (setq package-archives …) (package-refresh)) with package-refresh a new function that builds atop a previous package-initialize call.
* What if I *don't want* to use package.el at all? We could recognize a special dot-file in .emacs.d to disable package.el entirely (say, .nopackage).
On the upside, we get a working configuration for everyone without having to require or insert package-initialize calls in the user's config.
Clément.
