I was going to add the exact same thing as @Freshmaker: it isn't actually needed, as the animation actually defeats ghosting in a much more efficient way than a full flash, and flashing can *NOT* be animated, so it would be *extremely* jarring

.
That said, I don't use nightmode myself, and nightmode being what it is, I'm willing to believe that it doesn't quite work as well there (especially given that the anim waveworm is not designed for that, so it makes perfect sense that stock would disable anims in night mode).
Making the anim toggle Dispatcher aware sounds good, though (please put that in a GitHub issue, it'll have a much better chance of not being lost to the void

).
