A "Concept Distro"

The other day Scott Remnant posted the idea of a concept distro and I think it is a pretty cool idea.

Something I think is pretty cool.  The idea is this distro could do wild and crazy without having to be responsible for bugs/triage/etc. 

I think it is a pretty cool idea, make an entire distribution you do a bzr update to “checkout” or something similar

Would this concept distribution detract the core developers from the Ubuntu development process?  Or would it provide these developers something fun to do and to keep the creative juices flowing.

Anyway I thought it would be a cool idea
