And what is the benefit of that? Who would use that and for what? Containers solved deployment, and software distribution problems related to diversity of runtime environments on linux. It also has some security benefits, but their adoption was successful because it solved real world everyday problems. It eventually allowed better utilization of servers.

They did not have such success on windows, despite Windows also having a container subsystem, as windows servers already did this with IIS web app containerization.

On MacOS desktop software distribution is largely a solved problem since ages. On MacOS/Darwin servers... are there such in industrial use apart from some research installations?
