Transcoding content would also be significantly more effective with
declaratve animation.
Similarly, authoring and maintaining animated content can be more easily
fitted into a tool-independent workflow if the animation is declarative,
thus recognised by any tool, rather than based on analysing javascript to
understand what it does. This is particularly important for people who
primarily use WYSIWYG approaches to editing - i.e. the vast majority of
people who produce content.
Somewhat more implementation dependent (at least in theory, but therefore
perhaps not a strong primary use case), operating on devices with limited
capacity can be more efficient by using declarative animation hooked
directly to efficient native methods, rather than having to manipulate the
DOM (which can be realtively heavy on processing, battery, etc.).
