Indeed. Because doing this is asking for trouble: Emacs loads packages in a certain order to avoid several subtle problems; doing that in a different order defeats that. I think package.el should test with featurep whether a version of a package is already loaded, and refuse to load it into a running session, or at least display a warning to that effect, suggesting to restart Emacs.
