Personally I think it's the right move, imo 5 years too late. The view is shit from up there and there really is no benefit of having it open for 3/4 of the games when we were decent let alone now.
It's good they've consulted the ST's and seem to be going about it the right way.
Mizer, they said it will be open for select games (i.e, against the Tims i'd imagine).
