So, the system is full of users, each of whom want different features to be supported by the OS. And some features are needed to protect subsets of the users, while other users not so much. What seems to be happening is, some of the users don't want certain features implemented. In order to stop these features, they are claiming that the OS design specifically forbids these features.

But the OS is software. And the users collectively pay the contractors who write the software, and they can change it to say anything they want it to say, because the users are paying for it, and using it. Unlike religion, the design is not literally written in stone. The designers were well educated on the history of OS design, and knew that designs change over time. So their design allows for modifications without a total rewrite - something they saw as a feature.

So it seems to me the arguments and proclamations made by some users that "It's not in the design!!!" are equivalent to those made by, say, systemd opponents. There's a lot of people (myself included) that do not want systemd in their OS. But if all the other users vote and want systemd in the OS, I will capitulate and learn to deal with it.

We shouldn't get so caught up in the damn kernel or OS that we stop improving the whole system.
