There was not a specific poll if the layout should have centered prints or not (there were a lot of polls on a lot of keyboard topics though).
But, I searched for the statement that confirmed the keyboard layout and found what @iKirin stated some time end of March:
That from my perspective stops the discussion on the alignment of the keys and only puts focus on content.
I agree that the button is not fully self speaking, but as you don't have a single button keyboard you will always see the other buttons in parallel (imo). I'm open for having a strike-through on the mute button, don't get me wrong, but if Eve's decision is to keep it even more simple it does not harm the understanding of the key.
(Other than what some stated the F9 print does for example)
