What are your thoughts on purging mobile pests from live rock with hypersaline water?

Explanation from KP Aquatics:
"(Optional Step) Undesired critters (we really don’t like the word unwanted pests as every creature has a purpose in life) can be removed by submerging the live rock into a saltmix of 1.035 to 1.040 (Specific gravity) for one minute. You can leave it a little longer but it should do the trick for mantis shrimp, crabs and worms to vacate the rock. Please turn the live rock in the bucket for the salty saltwater to penetrate everywhere in the live rock. Afterwards you can evaluate which crabs to keep and which ones to permanently remove. You can repeat this step 2 to 3 times during the curing process (before, during and after). It will help with keeping the unwanted critters under control obviously it doesn’t guarantee 100% success but it should get very close to it."
