Sometimes the human is faster.

I've seen someone duplicate a class file (already filled with duplicate methods) rather than subclassing, and when called out on this it was because properties were private.

This was a team with just me and him in it, it didn't even really benefit from things being private.

That said, the really important lesson I've learned over the years is that terrible code and practices are almost irrelevant: this app won awards and was highly regarded.
