You don't want to pull and reshoe more often than necessary to avoid damage to hoof. Sliders are no different than regular shoes in that regard. If you don't want to wait for a break in the show/training season You can time trail riding with regular farrier care and when it's time to reshoe, just take a break before resetting to go trail riding. But that does mean two trips for the farrier.
My Reiner is out on pasture daily. No problems with her being turned out. Its a grassy gentle rollling pasture. But she is pastured by herself. BM decided to put her in a group one day, which shouldn't have happened, and there was a scuff between mares. The other mare required stitches. Any horse with rear shoes poses more of a risk, but sliders can do more damage than a reg shoe if another horse is kicked by them.
Sliders don't fit like a reg shoe. They extend past the rear of the hoof. It would make finding/fitting a hoof boot very difficult. If its even possible.
It's a lot like nuts and bolts - if the rider's nuts, the horse bolts! ~Nicholas Evans
