It is just a matter of time
There's a lot of desperate people whose families' life savings have gone on getting them to Belarus for this.
Iraqis can be very cynical people and there are far more people in Iraq who don't yet believe it's possible to cross into Schengen; they've heard about it and don't quite believe it. I've discussed this with Iraqi ex-colleagues who've messaged me knowing I live in PL and asking if it's true. I've told them that it's dangerous and that people have died trying to cross.
I've a feeling that the more people who can prove they've crossed that way, the more will hear about it back home and come.
