Is Fast Charging Killing the Battery? A 2-Year Test on 40 Phones (www.youtube.com)

TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.

And with that, hopefully we can put this argument to rest.

If engineers were the ones in control that would mean something.

As I see it, phone manufacturers have zero reasons to keep the battery degradation low, but many reasons to push advertised capacity and charging speed. If you were cynical, you could also assume that they're trying to make sure the battery doesn't last too long because they want to keep selling new phones.
