It depends. When it's wanted that packagers stumble over those
questions by a module, they shouldn't test in BATCH_MODE.
I think, enabling pkg_rr to use an .pkg_rr.rc from users home (or
$prefix/pkg_rr.rc), would be enough, because it already supports
pass-though -D flag.

Yes. That's what's I missed.

That happens automatically by the faked home dir. As long as we don't
put a CPAN confiig in it, any cpan download attempt will fail immediately.
Further, neither ExtUtils::MakeMaker nor Module::Build download anything
automatically from CPAN (newer M::B could, but ask back before and
have 'N' as default answer). Module::Install needs "--skipdeps" to avoid
any downloading action. People work on a better solution overall, because
I explain our (pkgsrc) point of view regulary in #toolchain on irc.perl.org.
