Yes, that’s a good point. If you a) can’t realistically train circling close to limits in the sim (which I agree with as if you start to use electronic aids and/or prompting from the back as opposed to looking out of the window, the mission has failed) and b) there is very little to no exposure on the line, logically you should be calling the whole thing into question.
We don’t circle in the USA due Ops Spec but can elsewhere, with 1,000’/minima. I used to do quite a bit when flying shorthaul in low-tech aircraft but now with an FMC/iPad full of RNP approaches, I haven’t needed to for a very long time. The guys I fly with are very likely in the same position, so if it was at all marginal, somewhere else with ILS/RNP would be looking much more attractive...
