In general, animations don't seem like a "power user" feature at all. Animations hint at new users ("hey, where did that window go when I minimized it") but aren't useful once you understand the abstraction.
On the first case animations aren't important, but on the second they are essential.
Look at tools, for example. Tools for power users do not have fewer cues and affordances than tools for neophytes. They have more, because they have more features, more power, and using them can be more dangerous. You can also see it that way: a newbie using a feature once a day will be wrong (and needing to be nudged to the right direction) once a day. A power user who is wrong 1 times every 100 they use a feature will still be wrong more often than the newbie if they use it more than 100 times a day.
Also, this:
> We’ve turned off the animation when switching Desktops using the keyboard shortcuts as it was leading to flashes and hangs
is fucking ridiculous. If your compositor is so bad you can’t animate desktop switching without “flashes and hangs”, it means you have some serious work to do on your display subsystem. Fix your OS already!
