It seems I missed the part to add default problem solutions in 
non-interactive mode.

Yeah, suppressing these is definitely a mistake, as we need to indicate 
(in a small number of cases) a package version which has no depends: 
when other versions do have them.

Unfortunately, fixing that reveals that the setup parser doesn't 
currently permit an empty requires: or depends: list (which I guess 
explains why they have been suppressed historically)
