This would be my concern. It would then become counterproductive.
I can see this being an effective bribe on WN but with assigned seats and no PDB for people in coach, who wants to board early except to find space for carryon bags unless the flight is so badly overbooked that you fear duplicate seat assignments.
Still, if DL were to try this, would the offer be to board after zone 1? If so, there wouldn't be many people for whom the offer to check something to board early would matter.
