You're specifying a new interface here, and updating pip itself is quite
easy. So why would you do things you're not happy about to support
"sufficiently old pip's"?

Isn't that something you can ignore? If the plan for pip anyway is to
always go sdist-wheel-install, why support this flag for a new build
interface?
