Well, I read it like "decenterring issues are not always existing". And I'm guessing as well the red-badge lenses might see tigther controls? Being the first red-badge lens in PZ-test, we'll have to wait how the XF 16-55mm F2.8 R LM WR or the 100-400/4.5-5.6 will stand.
Also, I take the liberty to disagree with your in terms of different speed at different sensor sizes because that's just not logic. If an exposure-meter tells me "1/60 sec @ f/4 @ ISO 200" it absolutley plays no role which size the film or the sensor behind that lens have. As long as the lens is made for the sensor proportion, that given shutter speed and f-stop will remain the same for a given EV. You will never be able to convince me of something else, simply because it's wrong.
