What I'm gathering here is that your argument simply boils down to that it's your personal preference (in this example) that rotating 90 degrees should have no associated animation.

> The actual job is not "feel" it is "do".

According to.. you? And subject to your expectations? If I click a button to rotate an image 90degrees on my phone's image editor, I personally expect (and want) it to have rotation animation.

So who's right? You, because you speak in absolutes?
