Touchy subject Bart so here is my 2 cents:
Sand beds can be beneficial if regular maint. is performed. Without that, it is my opinion that there is an element of risk involving nutrient build up. There are many people that disagree!
Sand-sifting creatures do not "clean" the sand but rather eat the benthic organisms within the sand bed and therefore are actually detrimental in relation to using sand as filtration zone. I would not use any myself.
In order to maintain a sand bed, I would make damn sur eit is fully accessible with no rocks etc. to block your view or ability to vacuum. I would remove and replace about 1/3 of the bed every six months. This helps to consistently provide new material for organism growth and nutrient absorption.
I would not swap sand or do any maintanance on the sand bed while it is in circulation. I would make sure that the bed can be completely isolated.
So, keep in mind this is my opnion based on personal experience and a lot of research. There are many successful DSB tanks around the World, so obviously it can be done that way as well. My opinion is that increases the risk of system failure and requires advanced reef keeping knowledge as well as various methods to keep nutrients in check.
