That makes no sense at all. Why should they not allow it? And who's to say someone is walking or just can't make up their minds. And at what point do you consider it walking? Let's say I want 10/24 - 10/30, but decided today to book starting 10/23. Would that not be allowed in your scenario?I think MS should find a way to not allow this but it is what it is for now
As an owner at both resorts, I'm ALL for walking at 11m for VGF-standard studio and AVK-club

And not everyone needs to buy where they want to stay, that's the beauty of DVC (and many other timeshares). You're not locked into staying at 1 resort forever. Wanting to "stay somewhere different" is not the same as "must stay there". Both groups of people would book at 7m.
