But the important thing, surely, is what the DOT's opinion is.
We can see an established and continuing adoption of the practice that cabin baggage limitations are those set by the operating airline, and that the marketing carrier notifies customers and passengers of this by a generalised reference on the website.
We can see the DOT having been interested in certain issues connected with codeshare operations 6 years ago, and having approved this particular JB with the condition that you kindly drew attention to. The condition says nothing specifically about cabin baggage, let alone that the marketing airline's limitations apply unless expressly and specifically displaced. All the condition says is that the marketing airline must "accept responsibility" for the whole journey even if operated by other airlines; ie it can't shirk its contractual responsibilities by saying "we subcontracted this bit of your journey to someone else".
And we can presume that the DOT is not in dispute with the marketing airline about the practice of putting up a generalised statement about cabin baggage limitations being those of the operating airline. Otherwise, six years would surely have been enough for that to have been sorted out.
So it seems to me pretty clear that the DOT doesn't think there's any contravention of the requirement.
And even if, hypothetically, there were, it remains the case that the practice is that the operating airline's limitations apply.
