Actually, I think the reason you can use the luggage check in is that it is run by a different company (There are companies the TSA has approved to do this, they use them at other hotels around the country) and of course it's actually paid for by the participating airlines. That's why SW and some others aren't participating. It costs money!
The Resort Airline Check-in Service is run by BAGS Inc. -- see

I wouldn't be so quick to say, "of course it's actually paid for by the participating airlines."
When BAGS, Inc. provides remote airline check-in service at places like the Orange County/Orlando Convention Center, the passenger has to pay for each checked bag.
At the Disney resorts, I'm sure that Disney is paying a negotiated volume rate to BAGS, Inc. What's in it for Disney? The answer is that Disney is doing everything they can to fill on-site rooms, without having to turn to heavy discounting, by providing compelling reasons for guests to stay on site -- and especially for guests to stay on-site without a rental car.
I'm sure that Disney is spending a fortune on Magical Express and Resort Airline Check-in, but they'll make even more money through increased room yield and onsite spending on dining and shopping.
American Airlines is doing everything they can to cut costs. They eliminated meals on all domestic flights -- even from Chicago to Hawaii. They even eliminated pillows and blankets from all but the longest flights. American would not take on new costs for remote airline check-in -- especially for Orlando passengers visting WDW, most of whom are flying on deeply discounted leisure tickets. And the other airlines are cutting costs and watching expenses along similar lines.
So why are some airlines participating and other airlines not participating in Remote Airline Check-in? It may have to do with factors like baggage lability and with computer interfaces between the airline and BAGS, Inc.
