Yes because the reason you'll usually be held is that another aircraft is cleared for the approach ahead of you. So like landings at towered airports only one aircraft is cleared for the full approach at a time. If the approach is open they'll just clear you straight into it with at most the procedural turn being required as far as a hold might go. And that approach is also held for you until you close your flight plan if you're at an uncontrolledly airport, so don't forget to give them a call either just before (visibility permitting of course) or right after you are on the ground or you'll have some very irritated people behind you. You can deviate from the time constraints too if you reach bingo fuel but that is basically an emergency situation at that point.
