replacing the entire piece of wire may be 'better' but repairing with tubing can be 'acceptable or safe practice'. repairs with shrink tubing are made all the time in the industrial world for these types of incidents. if doing a shrink repair, it is important to use an appropriate tubing, one with a ul listing that has a voltage rating. also need to prepare the conductor and apply the tubing in accordance with the manufacturer's instructions. installed in such a manner, the tubing repair is totally fine. the problem comes in when joe homeowner is using some cheap tubing off of ebay or not installing it in the correct manner.
i'm with you though, i would replace the entire conductor for such a short length and small gauge.
Don't know where you work, but make sure you have plenty fire extinguishers, because that's the dumbest thing I have heard today. Please explain why you do this to OSHA or the insurance company when something bad happens. Your changing the UL listing for the wire if you melt off the insulation and put on heat shrink. Do they sell THHN etc heat shrink? Hell no, because you replace the wire!!!!!! After the heat required to melt insulation, the properties of the wire change, resistance goes up and..... Uhhhhhh forget it.
