Suggestion: could it be done as a page in the modularity documentation
instead of (or in addition to) a blog post? That would make it easier
to discover later if people wonder about these things.

Extra suggestion: Stephen's requirements blog post would also be
excellent to archive in the modularity docs. Stephen, if you don't have
the time or inclination, I'd be happy to try to figure out how to get
it in there for you.
