Another advantage of a trust is that other trustees can have the guns, so my son or daughter can take any of my NFA guns out without me being present. My son does like to shoot my Thompson and coult have it even if I'm not around.
The other advantage, as stated, is that the CLEO does not have to sign off. The fingerprint requirement is a bit of a hassle but I can deal with that. Go to any place that does passport photos and have a dozen or so run off for a few bucks, no problem there.
Remember, the CLEO thing now will be that he is just sent a copy of the approved form, and he doesn't have the opportunity to ignore it and not sign off.
