Thanks for the info.

I doubt this is a problem in practice. If you get Org from ELPA, it
compiles files with your current Emacs. If you get it from an archive or
directly from git repository, you have to compile files yourself anyway.

Using Linux distribution packaging system is not among suggested
installation methods in the manual.
