Solving it per-application would be counterproductive in four ways. First, it would be inconsistent: apps would use slightly different colors and icons, different animations, and different sound effects to indicate input errors. Second, an app hard-coding an error color and/or error icon would risk clashing with a future iteration of the Ubuntu theme. Third, most app developers would not know or bother to provide audio feedback of errors for people who can't see. And fourth, even if an app developer did all of those things perfectly, it would be much more work for them than just setting an error class.
