If this proves popular, we might start seeing some flights that run of overhead space in the middle of Main Cabin 1 boarding!

What's DL's goal here? Is it to attract passengers who fly multiple times per year, but not enough for to attain status to get some set of perks to try to get their business loyalty? Or I wonder if this is a test run before making FO status harder to achieve (some discussion about that has been going on in the UA changes thread)...it sort of provides a soft landing for folks who would no longer qualify for FO, or a informal half-status in between FO and general member.
