Normal engine temp?
Your theory is sound and if this mod had cost any money or had been difficult to correct, I wouldn't have done it. But the results don't support your theory unless there are other factors at play or the loss in airflow was so slight it was negligible.
I have noticed the need to clean the engine compartment more often though....

I found the link to the data that I referenced in my original response.

If you look at the settings you should see that when stationary they are trying to keep the coolant between 219F and 226F.
If you go above 35mph, the fans turn off, and don't turn back on until you slow down or the coolant hits 246F.
I don't know why they chose to design for that high of an operating temp, but it was deliberate.

So I guess the reason I haven't noticed an increase in operating temperature would be....?

I think the air flow issue you've pointed out is definitely an issue on cars without much frontal area for air flow....meaning Vettes and older F-bodies. But comparing the grill openings on the V1 with the "open" surface area of the radiator, I don't think removing the weatherstrips had any noticeable affect on the cooling system because the radiator is getting all the fresh air it can handle.
Cooking everything under the hood makes no sense to me. Baked wiring harnesses and crumbling plastic makes for a car that can be hard to work with so I see no reason to take that chance if there is an easy out. I have a feeling that decreasing under hood temps wouldn't hurt on the dyno either.

GM plastic is brittle everywhere. I don't think that's a heat thing. They've always been like that.

I think I only see 210 sitting in traffic in August.

It is warmer than I am used to with engines but it is what I have noticed and corresponds to what some of the better tuners suggest. That is why I am on the stock thermostat and have the fans programmed a little differently than stock.
