First of all this is in the wrong sub-category.
There is a sub-category called Suggestions for a reason.
Secondly, if Trent were to develop this into Minehut, I'd doubt he'd make it free.
If Minehut wished to create more income, they'd sell server icons to the ranked players, or using credits.
Overall, Minehut wont give free benefits towards Server Icons, as it'd be a loss of income.
