The thing is, need of overhaul is overestimated by Paradox Plaza residents. In every game and in almost every hot topic. According to SteamDB, Victoria has slighty more than half of Stellaris active players. Half. Even with all overhauls that Stellaris got. Even with more DLCs and more renewed interest that they bring to Stellaris. That is hardly sign of game that is in dire need for overhaul in its core systems.
Also, I do not agree that bad overhaul is better than no overhaul. For me at least, Megacorp was the point where Stellaris lost its appeal. Before Megacorp, economy wasn't great, but it didn't bothered me so much. After Megacorp, it actively impede my fun.
