Aren't we going to use separate wikis per project? What are namespaces intended for?

I was thinking it would be easier at first to develop several projects as namespaces, which might be easier to support socially, and then "graduate" the more developed ones over time. Especially for the low-tech "spores".

Hosting multiples "spores" on one wiki to start also means we only have to propose one Wikidata identifier property, which is a more modest ask of that community.

SpecialNamespaces has been installed, and we have a runbook on how to use it. Can we resolve this task or should we keep it for tracking actually adding some namespaces?

Maybe we can close it, and open another one for the fancier namespace extension if we ever get to that. Indivisual namespaces are easy enough now that maybe we don't need to track on phabricator.
