So this could potentially end up excluding partner "Light" fares from MM credit as they could certainly be considered to be "similar" to DL BE fares. As also noted above, AF/KL don't have a separate booking class for their "Light" fares (you can only distinguish them by their 8 letter fare basis codes which have a 'B' in second to last letter). So DL may not be able to tell them apart from their regular Economy fares. VS has a separate booking class for their "Economy Light" fares ('T') which would presumably make it easier for DL to identify them as they don't need to look at the fare basis code.

I'd be hesitant to book a VS Economy Light fare until someone confirms these will earn MM miles. They do still earn redeemable miles towards Skymiles, so that is a difference betweem them and DL BE fares and perhaps they will earn MM miles too.
