User:RobLa-WMF/Headspace compatible

There's a term I've used for a while: "headspace compatible" (see an example in context), but web searching seems to indicate that I'm the only one that seems to use the term as of this writing. When I say this, I'm trying to describe the design equivalent of "backwards compatibility". That is: put things where people expect them to be because that's the tradition (e.g. clutch on the left, brake in the middle, gas on the right). In other words, do what people expect unless you have a really good reason to depart from convention.

The concept appears to be described pretty well in this design guide: http://www.w3.org/People/Bos/DesignGuide/compatibility.html

I found that making a search for the wordier term "backwards mental model compatibility". Is there a more mainstream term describing this concept?
