I think that's a good philosophy, but I think it is also good to provide 
a 'best practices' or maybe a better term would be 'reference 
implementation' of putting those lego blocks together? Just given a 
bucket of legos, it's hard to imagine what id possible without the 
little  catalog that comes with it right? :) And they are just as fun 
(although a different kind of fun) to build based off of the instruction 
booklet than to build from your own head. It certainly takes a lot more 
time and work to do the latter.

Anyhow, I see the UI/workflow pulp thing I'm talking about as being sort 
of what you get if you follow the lego leaflet instructions maybe...?

I would think adding more repo functionality to it, though, it would
grow more complex than what is there in it right now. I don't know for 
sure though, but looking at spacewalk's complexity it seems a reasonable

Is that the bucket the cow kicked after it ate the horse? :)

Okay, I understand now, although I'm still not sure I agree or disagree

Yeh, but I think where you say "perspective" I'm thinking different UI / 
different workflow. Although then they could be tied together in 
different tabs and look the same so they could "look" like perspectives 
- but essentially they would be different UIs developed as such.
