It's really not that complex of a business rule for them to figure out that once you say you have a green card and you enter a valid GC number, you don't have to present any proof of onward/return travel. Clearly a bug
These kind of things kind of irritate me but the truth is one normally always have bags going overseas and if you are 1K you are not waiting in long lines generally.
I know a lot of people who travel overseas with just a carry-on. And it's not a just a matter of waiting in lines. Avoiding the check-in cut-off and getting upgrades are other reasons.
