If you had spent as many hours as the Sages have here helping people understand why they were getting holes and missing edge segments in their small models, you would welcome this change. Yes, in older versions you could draw small arcs and circles with large numbers of segments but more often than not those tiny little segments created issues that resulted in groups and components not being watertight.
Even if you could still use larger number of sides on arcs and circles, you’d have to scale up at some point to avoid the gaps, anyway. There’s no change to that.
