I think it's nuts, but that's just me. There's a few fixes around to run coolant around 200, which is on my to-do list.
Interested in why you think it's nuts. Do you have other engine modifications that push you towards running it cooler? Or is it just a predisposition to run at the temperatures we used to run in older technology engines, on lower specification oils? The earlier generation engine you speak of with a 195 C thermostat was probably using a lube oil from the late 1980s or early 1990s, I'd guess.

I like it hotter. Keeps the oil cleaner, burns off the condensation, and so on. Means you have to use a correct antifreeze glycol mixture instead of straight water, and have a functioning radiator cap, but I take those as givens, for a variety of other reasons.
