I know sometimes new designs need some time to "grow on you". I do not believe this is one of those times.
It's painfully bad enough that I have to assume it will change before release.
It could very likely be a placeholder.
I know Apple can be pretty staid but for a beta I am assuming (and hoping) that they're taking the piss on that.
I suspect that even if it wasn't intended to be a placeholder, after the reaction that icon in particular has gotten across the internet, it's a placeholder now. :)
This one may grow on me, like a tumor.
Yeah, I just got a call from the nineties about it... Guess what?
