I saw this as well earlier. It essentially seems like just a bundled package - instead of just buying MCE, you're buying a package which includes MCE, similar to how Frontier sells "The Works," for example.

I'm new to AA, but it seems like this is something that's a part of their approach - figuring out how to sell upgrades in various ways (e.g., instead of upgrading elites, offering discounted upsells to Business/First last minute via app).

The only concern for those with elite status would be if more people choose these options than currently do, therefore leaving fewer MCE seats to select for free, more people in the "priority line," etc. However, as has been the case with the LP system and credit card spend, the frequent business traveler will likely already have status and therefore be competing for those resources, and they seem to be marketing this to those business travelers, so not entirely sure the point here.
