Is that really a good idea?

I mean, you of course can set up a project type like that yourself.

But if it's included in project.el, it means we're taking it seriously. 
And there's no way to specify the ignored files, say. And file 
enumeration will inevitably be slower than in VC-based projects.

Do you have a lot of projects that aren't backed by VC repositories?
