The wings don't care how it feels to the pilot!
The physics is well understood, but not by most non-aeronautical engineers.

There's still a lot of undiscovered stuff, and a lot of experimenting in wind tunnels. Winglets and strakes, for example.

We were talking about absolute basics that were /very/ well understood by the 1940s (see "Stick and Rudder", chapter 9, 1944, still in print!). By comparison winglets and strakes are merely optimisation tweaks :)
But winglets have been around for a long time; apparently some WW2 bombers had them then. The modern variants were first described in the mid 70s, but only took off (ho ho) in the early 90s (on gliders, naturally).
