All my bikes have had toe overlap.
If I'm u-turning within a single lane, I need to coast around the bend. (And I'd worry about pedal strike here, too.) Otherwise, it's not a problem. With any reasonable speed, I've never bumped the wheel when taking a sharp, precise turn, like from a road onto a narrow sidewalk intersecting the road.

I can see that having to pedal at very slow speeds through a 90 degree bend would be difficult. And I've bumped my shoe a few times riding slowly uphill on loose gravel, where I needed much bigger steering inputs. That was annoying and a bit dangerous, but I didn't lose control.
