It's not really only about cooling though. The energy cost is going insane right now and most people would like to not make their rooms hotter. Bumping the TDP also impacts laptops. How will Zen 4 mobile chips work with low TDP? It's, sadly, a bad move from AMD. They sould have kept their 65w x600-x700 lineup and their 105w x800 and x900 imho.
