If it messes up other things, they're inaccessible. Mostly it makes everything that respects it much more pleasant to use. IIRC things that don't respect it will use their 'normal' animations and that is what it is... unlike disabling animation in Android with developer tools, that removes almost all animations, but breaks a meaningful amount of software that monitors animation to trigger behavior... You can get stuck in pages where the animation done never fired.
However I am concerned that it may affect and mess up other things.
