I see no reason for D rings unless you want to quickly clip a Dutch Stinger or a Carabinier. If the rings fail you will have to fix it like you did. Subjecting the tarp to the damage anyway. It may prolong the damage to the tarp, but not with out the cost of being a weight penalty and having to re rig your tarp twice.
On a related side note: I'm debating cutting all the D rings off of my Incubator, only thing hold ding me back is resale value, when the next greatest thing comes out...
