It also depends on what RPM you're engine braking at. Many (modern) cars completely cut fuel above 1500ish RPM, but have a wee bit of fuel injected below 1500ish RPM, presumably to ease the transition/surging going back on throttle.
Vista Blue has it. The only time you press in the clutch is when changing gears or just before you come to a complete stop and on the rare occasion where it simply convenient to coast.

Leaving the clutch in while you brake is not causing additional wear any more than routine driving is.

There are those who routinely down shift to stop instead of letting the brakes do the majority of the work. While down shifting is useful in situations like a long mountain descent or during racing, it is sort of ridiculous to trade less wear on the brakes for more wear on the clutch during routine driving.

I step on the clutch when slowing down to take advantage of idle RPMs. It saves gas. I know, I know, it is only a few atomized drops saved but over time it does add up.

Of course, I leave the stick in gear while slowing down. It's only safe.
