In VGC, the matches are far too fast-paced to run SR, as no one really switches out or anything.
However, in 6v6 Standard Doubles, a LOT of switching can occur, from Weather Wars, to Volt-Turning (which is a totally viable strategy here too, as Pwne discovered), to just eliminating bad matchups. After all, Protect-Stalling only works so often.
Therefore, I try to set up Rocks if I see a couple mons I feel I'll either have issues with later, or weak to it, especially if the Genies are out, or even Volcarona, who stomps on a lot of teams, especially with limited Rocks users and a powerful spread move available.
Now, SR isn't nearly as powerful here as it is in Singles, where you HAVE to switch a bunch, which is why I don't use Spikes, but SR can help break Sashes (which are super common actually) and Sturdy, as well as turn 2/3HKOs into 1/2HKOs on the regular against several opponents.
YMMV, but I feel SR has a place in 6v6, just like Spread moves, wide guard, helping hand, and Protect.
