Hader's command issues are not so severe that they cannot be overcome. The numbers don't show it as much but Sale had some command issues early on too as did Johnson. In fact some wildness can be an asset. It makes hitters a little skittish. Hader's delivery is similar to Sale's and his stuff is close. Nobody is saying he's the next Sale nor certainly not Johnson who was unique but his ceiling is too high not to see how he can do as a starter. They have the luxury to make that move and see. If the 2018 season started tomorrow I'd go with Anderson, Nelson, Davies, Woordruff and Hader. Things almost never work out that simply due to injuries etc. so it's almost impossible to predict. Brewers easily have 4-5 other options at this point. Who those guys are will likely change between now and spring too with trades, FA additions etc.
