"... why are there bugs for V2 & V2+15"? The reason is simple:
V2 = initial climb speed with one engine inoperative, failure occurring before reaching V2
V2 + 15 = initial climb speed with all engines operating
The airplane must not be flown deliberately above or below those speeds in each condition.
Yes, the approved initial climb speed with all engines operating must provide manoeuvring capapability for up to 40 degrees of bank without encountering stall warning or other characteristics that might interfere with normal manoeuvring (ref. FAR 25.143(g)).
