I agree that there's little or nothing to be gained for a
marginally-cooled engine by running a lower-temp thermo, but but I'm not
yet hearing about doing so being "[...] actively harmful to the engine."

I need a good reason to yank the low-temp one and put in the 87C one
because on a 1.9 that's not particularly easy, in fact it's such a pain
I'd pay a shop to do it.
