Given the concerns and requests for additional documentation I think
that the maintenance burden of tutorials are well within bounds of
"necessary maintenance" for the project as a whole. Hopefully API and
other updates won't feel too onerous and the additional benefits will
prove out.

... and as Dave followed up as I was writing this - I see these as
tests as well.

I would be entirely up for having them built all the time (along with
the all of the other tutorials).
