Back in SB there was actually a NEED to voke->shirk, due to stances still reducing damage, etc., but even coming back to the game in 480 crafted gear tanking with 500 players, I had literally no problems managing hate. Even in tank swaps, just turn it off and you're fine 95% of the time (the other 5% being if the other tank literally does nothing).

Arm's Length is admittedly used a lot NOW, because it was ADDED in ShB.

And you haven't been raiding that long if you think stuns have never been used in raid tiers. Hell, even Low Blow itself had a specific purpose in stunning arms in A4S when it came out as part of DRK's first kit. Stuns were used more extensively than both Arm's Length and Interjects at some point.

One tier or expansion aren't the end all be all, and Cover can add more mechanics as well.
It isn't a question of what's inherently necessary. It's simply the easiest & safest way to do a tank swap for the tank taking aggro to voke while the tank swapping off then shirks to them.
