I know that NACA is famous for its ducts:
Gratuitous Ferrari F-40 from Wikipedia. Mmmm... pretty...
It is also well known for its airfoils, and many planes in the early years of aviation used NACA designed airfoils for their wings (for example the Piper Cherokee referenced here).

Do current aircraft manufacturers still use stock NACA airfoil designs, start with a NACA standard design then modify it to meet needs, or are the airfoils completely bespoke?
I'm asking about the major airliner manufacturers like Boeing & Airbus, regional jet builders like Embraer, as well as private/GA companies like Cessna, Gulfstream, and, of course Piper. Information on the (few, dozens, hundreds?) of other aircraft manufacturers (and kit designers) that don't pop to the top of my head is also welcome and appreciated.
Thinking about this further, I realize it could quickly devolve into a very broad
this aircraft uses a NACA standard wing,
that one doesn'tlist. That's not really my intent. A simple
yes, this aircraft/wing from 5-10 years ago uses a NACA standardwould answer the question completely, as would a
the last one I'm aware of is from 35+ years ago.
Also, the use of "modern" is rather vague as the Boeing 757 certainly feels "modern" (having been launched in 1982) but has been out of production since 2004, while the 747 started production in 1969 and is still being built. If someone wants to jump in to help define "modern", I'd take no offense.
