I've seen the same, although I generally use double crimp wire connections even on the smaller gauge wires. One crimp obviously attaches to the copper conductor the other crimp attaches to the wire insulation. Both Crimps are made with the same tool in the same crimping action. I suppose there is a small cost difference in the piece part, but it's a better, in my opinion, method for providing a secure double connection

The shrink-wrap must attached to both the wire and some other "thing" that holds the wire in place should the solder connection fail. I have seen the shrink wrap covering both the solder joint and the terminal such that the terminal is the other "thing" that holds the wire in place. The issue is that if the solder joint fails, the wire can contact some other potential that would create a dangerous situation. I have seen cabling used for this purpose. Note that the solder joint itself must be mechanically secure prior to soldering.
