Summary: See PHI774. Ref T13164. There is no reason projects //don't// support Spaces, just a vague concern that it's not hugely useful and might be a bit confusing. However, it's at least somewhat useful (to improve consistency and reduce special casing) and doesn't necessarily seem more confusing than Projects are anyway. Support is trivial from a technical point of view, so just hook it up. Test Plan: Created new projects, shifted projects between spaces. The support is all pretty much automatic.
