I agree, Stuart. Here is the email reply from my dealer:
"The Launch button you can use as much as you like on the 458 no clutch wear as dct gear box.
Your warranty will be fine."
On the phone, he did say that any abuse of a car, in general, will/may of course invalidate the warranty anyway... When I asked: define 'abuse' or 'excessive use', it is grey area...
Is it correct that the DCT/DCT-like cars are the only ones with official "Launch" button? I know that you can 'Launch' any car without a built in button to press, but my 612 (2008/58, so second generation 612) has one... Correctly if I am wrong, please!
