LGB,
When V1=Vr MOST operators simply call "Rotate", as V1 has already passed and is now redundant.
Regarding your comments regarding the "land ahead on long runways", fine, go ahead do it, just as soon as you've done the certification, test flying, approval by the regulatory authority, published the approved data in the AFM / AOM, trained your pilots in the procedures required, and had it approved by the regulatory authority for the country which you're operating in.
