I am unable to open either of the links from the original submission and am wondering whether it's noted that this is part of Matrix protocol specification version 1.1?

I was wondering, why would you move the "People" tab to settings instead of leaving it in the side panel and adding a new category for Access Requests in the same way as there is a category for invited people already?

Its not moved, the People right panel card remains, just won't show knocks to prevent noise/spam.

Settings already has a people section (people with non-default power levels) - this just extends that list.

it would actually be its own tab - the existing roles & permissions tab gets split in two for clarity. The member list on the right side of the room remains unchanged in any case, however.

Would it be interesting if members with enough privileges see the knock in the timeline?
