I am all for it.
The only draw back I see to this is that NGC will be getting more money out of us for grading our previously body-bagged coins. But that's OK because I get something worthwhile out of it as well. I havent' submitted a whole lot to NGC but I have received several body-bagged coins in return from what I have submitted.
Most of these coins were nothing overly special (just some of my first IHCs I'd purchased mainly). However, there was one coin (1913 $10 Indian Eagle) that my wife and I discovered while going through her grandmother's house when she passed at the age of 105. A true tricentenarian. We believe the coin was perhaps given to her by her parents.
I sent this coin into NGC about two years ago thinking is was going to get a grade somewhere around an MS62. Nope - bodybagged for "improper cleaing". We couldn't believe it. A great looking, now 96 year-old coin worth only it's weight in gold. Now we get the opportunity to have it encapsulated for our son, at least, and hopefully for several generations to come. I think it is a great opportunity. Not to mention the possible points it will add to my registry score, but it wlll actually be preserved for the future and hopefully because of this it won't end up in some melting pot for its content.
If you are leaving for PCGS, just remember that as far as they are concerned, this coin would only be authentic in its slab, no points in the registry and they charge more to do it. Basically, they've "Been there and Done that". Hasn't hurt that third party grading company, why is it going to hurt this one. ANACS does it as well. Both are still considered to be in the top 3, along with NGC.
My views only.
