Interesting… I learned exactly the opposite way and I’d argue it was easier. Feet on clutch and brake. Start the engine. Get used to the feeling. Gear stick into first. Back to neutral. Give it a wiggle, that’s how you know you’re in neutral. Practice changing from neutral to first and back. Foot off the brake, practice holding the engine at 1k, 1.5k, 2k rpm.
Talk through the next bit first: Hold engine at 1.5k rpm. Ease off clutch just enough to start engaging and rolling forwards. Back on the clutch then gently break to a stop. Repeat until confident.
Etc. etc. The whole time the learner is in control of the car and they learn the basics without having to worry about steering.
I think this is basically the same thing, just with the other steps included. On the right surface in first gear you don't need the brake, so just controlling the clutch is enough to move the car
