Really? ...give us some examples of what that risk could plausibly be.
There is a need to have flexibility considering DL's history of three main trends with their fleet (made even more pronounced post NW merger): 1. opportunistic fleet additions, 2. a tradition of flying the smallest/nimblest viable aircraft, and all coupled with 3. a desire to complete MX in-house and run that as a separate business.
You need #3 if you're going to continue to buy used aircraft and have mixed engines in your fleet. And you need #1 if you still find #2 produces the best margins. Finally you can't really do #1 if you don't have a decent relationship with the vendor. I'm sure Boeing will sell DL a depressed asset if they are truly desperate even though the relationship is terrible. That requires DL to be in good financial position when Boeing is desperate and its not smart to run your business based on lining up stars and the moon given how cyclical aviation is.
To give a better illustration of why Delta's behavior gives then reason to be on good terms with all major vendors: There is evidence that the 737NG (no idea on the Max) performs better on a CASM basis than the 320CEO on longer routes. Hence why you see the 321 rolling up and down the east coast from ATL but the 739 running out West. Similar patterns from DTW, at least pre-Covid. If 200ish fleets of both families produce similar overhead expenses compared to 400ish sized fleets, then running both types makes sense. And if running both makes sense, then maintaining relationships is in their interest.
another illustration: Also if Delta wants to be opportunistic in buying used aircraft, it makes sense for keeping relationships with all three (5 if you treat IAE and CFM as separate from the big 3) engine OEMs strong as well. That way DL can buy used 320s regardless of power plant. Look at their 767 fleet as an example.
