One of the key goals of the resource revamp is to spread out those large fights a bit and give smaller groups indirect impact to the front. That's while keeping players relatively in the same general vicinity but not all mashed up in one spot.
Not currently, that sort of flexible income makes it very difficult to balance and ensure meaningful and predictable consequences.
I'm sure we'll do something reasonable for deconstruct, but I wouldn't expect a full resource refund. When you pull a vehicle you're making an investment, and not all investments pay off, just like when you throw a grenade and it doesn't hit anything.
