Once you are type rated on an a/c IMHO you are qualified to Operate it , that's all factors of operatng it .
Personal experience from '73 , adhoc loading/de-icing earned you a Capt's recommedation on your file .
In '82ish , striking ramp workers nearly brought down our virtually bankrupt airline . The whole airline came in to do ramp work after/before shifts and days off .
Loading B4 flt and unloading after was normal , some pilots were honey cart trained , and top of the totem were those few trained on pushback /tugs .
Strike over , and 70's thoughts on strikes toned down , we went back to normal .
Highland and Islands routes was normal ops for one pilot to load / unload , one to do loadsheet . 1 CC clean cabin , 1 to check in pax and walk then to and fro .
IMHO 'preciousness' on an a/c has no place. Get the job done .
