This is along the lines of what I was thinking. Of course, the big
limitation is requirement org.el is not loaded. I would imagine it is
rare for org to be loaded and org.el not to be? However, I think this
sort of approach i.e. warning if there is an attempt to upgrade org when
org is already loaded, is the way to go.  Achieving this in a clean and
reliable manner is the challenge. False positives are an issue as that
would likely prevent legitimate upgrades.
