The variant itself is a good idea; but having default variants dynamically change has users unsuspectingly getting to build from source without expecting it. As we just discussed on IRC, why not just prompt the user to pick a variant rather than deciding for them? This ensures people get what they expect, and avoids running into bad assumptions.
