> I think developers are overly aware of the differences between native and non-native apps, and overestimate how much a casual app user cares about a native experience to be honest.

I would expect the opposite. They may not be able to put a name to the issues or even describe them, but I'd expect average people to show a clear preference for native apps basically every time in a side by side test.

I think developers tend to underestimate how important good UI responsiveness and feel is.
