Good point. Agreed that we should prune languishing subdomains from the
front page on some schedule.
<https://github.com/schemeorg/schemeorg/blob/master/projects.scm>
currently has a `display?` property for each project. If set to #f, the
project is hidden from the front page listing, but the DNS keeps working.

All of those are good ideas.

Perhaps we could use sub-sub-domains for experimental stuff in some
cases. discourse.forum.scheme.org etc
