[MCU] Would it make sense for Soul Stone to magically return to Vormir from time to time, or is that whole sacrifice thing forsaken forever until someone carries the stone back?

In the same way that it would make sense for a stack of cash to magically transport itself back into a safe after it's been removed. If the cash was magic, and also the safe was magic. 

In other words; You could think about Vormir like a lockbox, with magic wholly unrelated to the stone. Or you could think about the whole setup as being powered by the Soul stone. If the latter is the case, it might make sense for the Soul Stone to eventually retreat to Vormir under certain circumstances. 

That said, both Tony and the Hulk used the Soul stone without sacrificing anything directly, so if there is some process for the stone to return, it's not an immediate or simple one.
