I've not seen any response to this, but it seems to me to be a very valid 
point.

dash currently is optional, so there will be on a lot of existing systems 
on which it is not installed. How is the planned strategy going to 
prevent dash becoming the default shell on existing systems when it gets 
installed for the first time because of its raised priority?
