Valhalla updates are neat. It is not quite here yet to what it should be but looks close to it.
As for gates potential change. There are a number of proposed "solutions" in this thread and they all range from terrible (most of them) to irrelevant at best. The original idea is either irrelevant or slightly bad, depending on the exact chosen implementation. I don't have my own solution to the presented problem. At least I would advice to listen to what Ardennesss have to say on why current solution (or some modification of it) won't work as planned, as to me he looks like one of very very few people in this thread who have a clue about topic discussed.
