Until everyone has to look at this UI

Not classic.
I'm being snarky, classic means something different to each of us. For some when they stopped playing was when classic ended, others dislike features added in to improve the game (the "in my day we walked uphill both ways" syndrome) like pixels that makes people feel unique and special, to have been there and done that.
It's up to the team ultimately as they're doing it. But there is no reason we can't try and bounce ideas around.. this game is all about community after all.
