Indeed, many still do. So the paradox is that it will be easier to through check in from many secondary airline to BA than from BA to BA if on separate tickets!

I don't want to reopen this persistent point, but my understanding is still that there clearly isn't a OW protection on separate tickets. In a recent thread, we even had a very explicit statement from a BA agent that there isn't even a BA to BA one on separate tickets except in the case of long haul arrival to short haul departure, as a gesture of goodwill, and assuming the time between flights respects MCT.
