I rarely ever unhook, in fact when i do it is a such a rare situation I catch hell from the group we camp with, If you have auto level it may be a different situation, I manually level, by getting it close with blocks under wheels and fine tune with the jacks and fifth wheel stands, it is much more stable with the truck under it, no bouncing, if you are good it is level when you park and jacks only stabilize it. My theory is by staying hooked up it is one less chance to have a disconnect by unhooking and then hooking back up with interruptions of fellow campers making you forget a step and missing something.
I bet in the last 100 trips I have made over several decades I have unhooked 10 times.

level it with the unit hooked and good to go.
