Ha, sadly no! Whereas it's unacceptable for let's say an airplane to use euler, or a modern video game camera engine...
Most animation software used by artists/animators uses euler angles, and in order to deal with gimbal lock they just... Use a 2 or even 3-child hierarchy (they call it "controllers") where each controller animates one axis (or two). That's a huge overhead compared to just using quaternions, but if it makes animators more productive it's probably worth it. Computer vs Human time. Especially in situations where render farms are used and a frame takes an hour to be rendered, does it really matter?

So, it's not the animation applications fault. it's the animators who always prefer euler + messy scene hierarchy :)
I 've even see robotic arms be animated like that... robotic arms!
