After trying several more approaches, I now came up with yet another
idea. Instead of fiddling with load internals, compilation, or
load-path, what about making sure that Org libraries include version
info directly?

Every library will have

(require 'org-foo-9.X "org-foo")
(require 'org-bar-9.X "org-bar")
...
(provide 'org-lib)
(provide 'org-lib-9.X)

Then, we will make sure that the right version of the library is always
loaded. Simply because (provide 'org-lib-9.X) will be unique for
different Org releases.

There might still be a problem where we solve cyclic dependencies by
using declare-function, but those places should be fixed anyway, sooner
or later.

WDYT?
