You hit the nail on the head there. I think one of the main reasons that plus tires kind of failed is that you couldn’t put a 3.0 or 2.8 on an existing narrow rim without having to run the same psi as you did with a narrower tire to avoid the tire roll. That meant new rims and maybe frame too to fit wider tires. That limited the market to mostly new bikes.
PSI and casing construction determine contact patch size. I tried 2.8 Minions on a 30mm Internal rim and I found I needed the same pressure as I was using in a 2.4/2.5 Minions to avoid tire roll. All I was getting was extra weight.
