I do agree with you 100%
Even though the engine is done I do like testing and don't like the "what if" feelings that keep me up at night, if you know what I mean.
That's specifically what I was speaking to when I said something to the effect 'nothing is perfect' ...you will never, in my experience, not wonder 'what if' The time, testing facility and materials needed are not free. That said if you just want to regardless and it helps YOU in some way then by all means ...do it! I haven't look close enough to gage what I'd speculate the change will do. But while you're on dyno I would highly recommend moving the cam around, assuming you have adequate p2v.
