You guessed correctly. The gas flow is very low and I haven't had an issue, even at 0f. I do keep a couple of 1 lb bottles in the camper. I can use one of those if the big tank failed. They would be warm, for a while, and I could switch back and forth. I have a portable fire pit that sucks more fuel. It will freeze up a 1 lb bottle quickly, but the 10lb bottle will keep working, so volume must be important as well.

Worry, yes. However, with the 10lb tank, pretty full, I haven't had a problem with temps as low as -5f. I have a couple of 1lb tanks and an adapter that I can go to if my tank runs out, or maybe if I have a freeze up. My idea is that I could trade back and forth with one always warm in the camper. I have tested those in cold weather and they seem to work, but they do freeze up if hooked up to my grill or my fire pit. I think that the difference is, as you suggest, the very minimal flow that my little catalytic heater draws.

I've tried to write this 3 times! I did worry about cold propane when I started these adventures but haven't had a problem, in temps as low as -5f. The propane draw from my 3000 btu catalytic heater is minimal, to say the least. I keep a couple of 1lb bottles warm in the camper. They serve as backup if I run out of gas in the middle of the night. I was particularly worried about those freezing up but they passed a test on a single digit night.
