I have no strong preference either way.  Removing DRY_RUN may
simplify things in the code that gets used in the real life (as
opposed to the code that is only used during the tests), so I do not
mind it if it was done before the series as a preparation step.

I do not see it as odd at all; after all, nobody in the real-life
uses dry-run and as you can see its use is broken, or at least is
inconsistent with the rest of the system.
