Fair enough and my memory may be fuzzy but I see quite a few references to V1 as being the minimum single engine takeoff speed. https://skybrary.aero/bookshelf

  It's kind of poorly worded. Hitting V1 means you are committed to taking off, single engine failure or not - but you HAVE to reach V2 to safely climb on one engine. This should happen within moments of hitting Vr, but being single-engine after V1 means you went from hitting Vr halfway down the runway to potentially doing so at the ass-end of your minimum runway length. This means you have basically no room for any pilot error or other failures, and why engine failure on take-off is routinely rehearsed.

    Not sure where the original disagreement came from. I never said an aircraft should be able to take off at V1. Perhaps you took the "fly" literally which is fine but that was certainly not the intention.

  I don't have any specialist knowledge here, but that seems to make sense. If you're under V1 then you can still abort takeoff. Having that be the minimum for single-engine takeoff essentially sets up the rule that if you lose an engine while you can safely abort, then you must.
