People who exclusively use Excel spreadsheets to program is a good example. Most people who use spreadsheets never use functions in a cell whose effect is to change the function or value in another cell.
The only transgenes in use for plant crops are for pest resistance. I don't know if they have anything for growth habits or metabolic engineering. All of that is done with classical breeding, and I might add that recently breeders have been breeding towards less resistance to drought; high response to irrigation and fertilizer means less energy "wasted" as roots leaving more for seeds.
