Disagree - you are simply talking about degrees of failure. I think it is clear that the oil came from the gasket and it certainly did not look pristine. We are not talking about a flood of oil or even the noticeable drips I had from the seal on the sump on my SP2, but oil was escaping nonetheless.
As you say, and as I said, it is not a fix as the cause has not been established - it's pretty much a case of patch it up and hope for the best. Not great but it's Ducati's decision and if further issues arise then it's on them, as they are now aware of a problem and have decided simply to patch it up.
I have obviously made this point to the dealer - I expected the cause to be established and not for it to be simply put back together without figuring out the cause of the issue.
