That's a good summary of things to consider. With that in mind, it seems pretty nice if a library can make simple animations much easier. The demo shows some promising examples that tend to be common polish on, say, iOS. The simple sorting/delete ListView example is pretty nice compared to the instant changes with zero feedback it's compared to. Meanwhile, web animations by hand can take quite a bit of thought even for basic things, like fiddling with CSS `transition` and ensuring your component lifecycle sees it through. Always ends up being a bit brittle, like having to duplicate CSS time durations with your JS components. I'll have to play with it.
