With a dummy package we can have doctests, with #optional tag, checking that this all works. No, that's not true. 1) For dummy packages, there is no stamp file in local/var/lib/sage/installed/, which is where our "# optional" tags have traditionally come from. For example, pandoc is a dummy package, and you won't see it there whether it's installed in the system or not. 2) "# optional" tags can be established by runtime Feature tests.
