Some time ago we suggested to use a label for issues which modify the management 
model [1]. Having such a label extremely simplifies the planning for HAL. 

Now that I've done the planing for HAL for WildFly 18/19, I've introduced 
the label 'affects-model' and added this label to to all issues which are 
part of the HAL roadmap. 

I encourage all of you to use this label when you plan your RFEs. 
This will make my life much easier!

Thanks
Harald
