These standards do not apply to playerworlds already in Classic status. While we are encouraging them to update their servers, for many such as UN its a monumental task to redo everything on the server from scratch without sufficient staffing to do so. Its known as being grandfathered in and there are certain exceptions you must consider in fairness to all.
A new server being built will have already started with GS2 so won't run into the difficulties an older server might have. This is also why we don't encourage remakes of old servers. Many people think that just because a server was popular and playable 8 years ago it will be again by just uploading old content.
