Yeah.  I think we've largely adopted the position that contrib should
contain installable modules that do something potentially useful to
end-users.  A pure skeleton wouldn't be that, but if it's fleshed out
enough to be test code for some core features then src/test/modules
could be a reasonable home.

Great!  I'll put a patch together that adds the skeleton object to src/test/modules and I'll write some expected tests that run the expansion through its paces, when the support function feature happens I'll update it to include tests for that.
