To give some historical perspective (and current, but not on desktops
most people on this list care about, but are in fact important in the
market), many of the hints enable specialized behavior in specialized
circumstances where you may be running a custom(ized) window manager.
Think about process control environments (e.g. mission control at NASA,
or a nuclear reactor); the hints enable policies like: "This application
will *always* be available and not an icon". This may be a fundamental
safety issue.
Just because a conventional Gnome or KDE desktop doesn't need a hint
doesn't mean it isn't absolutely vital in other environments.
Bottom line: think beyond the conventional desktop use of X....
