It appears to be Delta specific now. In the past, I have come across this with airlines when I tried checking my bags through using two separate tickets on two airlines (not nested). But they were able to work around. But Delta seems to have taken steps to make that impossible.
If you have segments on another airline, DL agents said, there won;t be a problem. It's only when you have more than three segments on DL that you face a wall.
