No, it isn't. Even if you are rev matching it isn't going to be perfect. Brake pads are cheaper than a fucking clutch.
There's zero reason to downshift sequentially other than being able to accelate quickly if needed, but you can generally shift into whatever gear you need should such a situation arise and if you don't have time to it's not like an automatic tranny is going to save you either if you're in 4th for example but maybe you could accelerate quicker in 2nd. An auto isn't necessarily going to do any better.
It's a balance of practicality and safety depending on the situation. If someone is riding your ass and might rear end you, it's generally good to be tapping your brakes so they see your tailights and not just relying on engine braking / downshifting, but you also do want to be sequentially downshifting in said situation so you can accelerate if it looks like they are going to hit you.
If there's no traffic around it's pointless to downshift all 6 gears lol.
Everyone is free to do whatever shortcut they want. I'm just telling you the best practice. If you find downshifting such a bother, and never want to practice so that it is easy, then that's your prerogative.
