Jim, I know there is no reason to rev match but have found when doing so when aggressively (two to three gears) downshifting reduces the lash clunk and the irritation the sudden jolt brings to my wife!
BTW when I see cars close behind me I always touch to illuminate the brake to lamps.

In traffic I use the brakes. I engine brake in the mountains with no worry because there's never anyone in my mirror.

Rick, many of us have added a device like the Volo Module/Light to signal traffic behind you that you're slowing down when you are dropping gears. I think it's one of best safety additions on the market today.

Like SmokinJoe, I like to rev match when down shifting. It makes a smoother transmission match with one or two gear down shifts. The slipper clutch works great for multiple down shifts, before letting the clutch out. But by rev matching, it's a smoother transition and the clutch isn't slipping as much which I like to think is giving the clutch friction plates a longer life.

I paddle my big hairy flat feet to provide forward motion, then lock my knees straight, hold tight to the handlebars, and dig my heels into the ground to stop.

It provides me with daily exercise and lessens any wear and tear on the bike.

I would also like to rev match. As a matter of fact, I rev match both while up-shifting (when I am lazy and shifting slowly) and down-shifting (all the time) in my car. But my car has a heavy(er) flywheel which keeps the rev-s up for a little while when I am letting out the clutch pedal to catch the needle properly. For the bike however, the revs fall super quick as soon as I let go the throttle. At least quicker than I can catch the needle on its way down.

Speaking of longevity of friction plates, does no rev-match shifts with slipper clutch affect that?

Think about this the next time you come into a corner or a round about. Click down twice and let the clutch out, at any rpm, no need to rev the engine.
Thanks Jim. I didn't realize that. Good technique.

When the slipper clutch is slipping - the clutch plates are wearing. Plus there's a lot of drag on the rear tire which increases wear. It's not enough drag to cause the rear tire to lose traction but it's enough drag to cause increased wear. I like to think of the slipper clutch as a safety feature, and I mostly ignore it and rev-match when down shifting. Habit I guess.

I can come down a mountain with cars in front of me that ride the brake all the way down and not even hit the brakes due to great engine braking. Use it.
