I've seen this going around too. It's to do with all the build up of 'stuff' being good for the plant roots, but OP's plant is sitting above the substrate on a husk so gravel vacuuming will be fine for them. I vacuum my gravel once a week, focusing on either the left or right side of the tank, not going too deep into the gravel around the plant roots. But that's also to keep the fish good and healthy.
