I think the root of the problem is that you are confusing a minimum with an instruction. V2+x (depending on type) is the minimum safe speed for flap retraction, in the same way as Vfe is the maximum for extension. Do you always extend flaps at Vfe as you slow down?
Good luck with a meeting with FSI; unfortunately a large part of the problem is that they don't understand it either so you will not get an authoritative answer even if they sound definitive.
Bear in mind that the checklists are written as a follow up to you having done everything, so by the time you get to reading a checklist which may or may not mention a height or a speed you will be long past it.
That also opens the can of worms of why are they still teaching read and do checklists decades after manufacturers changed to scan flows and challenge and response?
May be able to add some more definitive references later, but I need to go and earn a crust now!
