Many developers still think software is feature-driven. So they want all
these nice buttons eg. "Hurt me", "Hit me!"  so they can tell their boss
their users have "choice". Then the users cry about their pain.

It's really hard to tell naive users with an uncalibrated screen that if
they have color issues on a color-managed printer then the right place to
fix them is in a graphics app. Most users want print controls which
basically fix their wrong screen profile.
