That would be very bad for projects that not only use dual licenses but especially if one of them is a commercial license. If you just checked there and found the apache and think "Great, I can put that into my closed source tool" you might be in for a surprise when the author contacts you and tells you that the apache is only for non commercial use and there is a second, paid license for commercial use available that you should have taken.

Surely doing that would require them to rewrite the Apache license (thus making it no longer the apache license) otherwise there's no legal way of enforcing the non-commercial use?
