What kind of changes are we talking about here? What exactly falls under the category of "design" decisions? Because, for example, my Gerrit change that converts Special:Userlogin into a FormSpecialPage is a design change (in the software sense of the word), but the change based on it to add the VForm version of the login page is also a design change (in the graphical sense of the word).
I'm very hesitant to support some sort of complicated approval process for submitting changes to the core, primarily because it already takes an extraordinary amount of time to get changes submitted.
