Just look at the comments of 
http://robotics.stackexchange.com/questions/3091/how-to-overwrite-default-git-source-in-autoproj

"This is not a robotics-related question. [...]"

Yes, this is the question if the behaviour is desired and the answer to 
it determines if it is a bug (not desired behaviour) or if there should 
be a feature request if this is the currently desired behaviour.

I think it is a development related question and that we should not spam 
stackexchange with this kind of questions.

Is there a guide on where to ask what kind of questions?

Nevertheless, I asked the same question about the behaviour of autoproj 
snapshot on stackexchange.

Christian
