[ Side note: all ELPA packages that use a `<pkg>-loaddefs.el` also use
  a `<pkg>-autoloads.el`.  ]

I don't know what you mean to say by that.

`org-loaddefs.el` shouldn't be any different from any other `org*.el`
file, in this respect: if it's been loaded before the package is
activated, then (hopefully) `package--reload-previously-loaded` should
reload the newer file.

[ I've heard various reports over the years that indicate that
  `package--reload-previously-loaded` doesn't always do that, but
  I don't know if it's because it's not called at all, or because it's
  called but makes wrong decisions.
  Also of course, there can be lots of cases where reloading a file isn't
  sufficient. ]
