I've been involved in most of those discussions, I don't need to search. None have suggested to me (certainly haven't "proven conclusively") that 0w20 with an oil cooler was "most ideal".
FWIW my '17 got up to 275F indicated (reportedly this is ~255F sump temp) every single session for 5 years, around 50 or so track days, +80k street miles. The car never needed an oil cooler, but I did run high(ish) 3.7cP HTHS 5w30 Redline oil during track season.
