The issue being that, for a lot of people, they often work a little too well.

If you're going to follow the philosophy that caring about the correctness, lack of duplication and security of an installed application is too esoteric to be relevant, I'll remind you that you're entirely free to do that to any extent you like with linux. Equally people like me are free to tell people who do that that they will receive no support from me for such a setup.
