We had an unusually cold day or two this winter (zone 8, bordering on 9) when

I lost a large Rosemary bush, and I guess I had forgotten that it was a bit
tender (others in less exposed locations came through without blinking).

Do you mean the bush is obviously dead? Or are you wondering if it
might be? My late, lamented rosemary bush (it died of disease, not
cold) was against a west-facing brick wall and survived -19C one
winter. The bigger the bush, the better its chances, of course.

Do people in less clement areas normally keep Roesmary as a pot plant?

Often.
