I used my last D01 in March. I would not hesitate using D02 going forward, and would consider reasonable third party parts if need be. I don't even replace the drain plug crush washer. The most I got out of a crush washer was maybe eight oil changes before the bike changed ownership. Some of my bikes lost the crush washer, so I didn't bother replacing it. Never had an oil leak, nor a stripped oil pan bolt or mating surface. Everything hand tightened. I don't over-think things. There are other life issues that require that energy.
