It absolutely would. As would teaching approaches in IMC, getting into ice & already knowing how to get out, and talking to FSS en route in order to make it around thunderstorms.

It's called gaining situational awareness. Unfortunately, Mr. Renslow lacked SA on that fateful evening. So did the pilots if AF 447. Both of those PIC's came from a non CFI environment. Our hands get held in the US 121 environment, but not in the Part 91 environment. Flight Instruction taught me an incredible amount of situational awareness.
