at the very least it is serving as a reminder to all other mining pools that total transaction fee revenue is not the only game theoretic metric that mining pools should be concerned with, when it comes to constructing their block templates.

if, in persuit of maximum fees, and at the exclusion of economic bitcoin transactions, pools opt to fill blocks full of jpegs, it's quite possible they end up causing long term harm to the network, and those higher fees ultimately become worth(much)less.
