It sounds like you think the painting's age means that it no longer has power, or at least, not power enough to warrant a content-warning. I would beg to differ, and argue that the fact that it still has the power to shock is what makes it "world-renowned".
Personally a mixture of the two suits me best. I appreciate the time by myself, but every now and then I want to go into the office to reconnect with other people. It can also make rubber-ducking more efficient if said duck is sitting next to you.
