Any time I’ve had a car with a manual transmission, I’ve used engine braking to help slow the car. If it put more wear on the clutch, it wasn’t enough that I noticed; in fact I got over 145,000 miles on one of the clutches in my current car.
I went 184k on a manual Honda with no appreciable clutch wear before it was totaled in an accident. They don’t teach you rev matching and heel-toe in HS, it’s up to you.
