Everyone (anyone: admin, user, unregistered and others) is allowed to make any changes that they like, but they should know that others have the right to revert it (and disagree ofcourse, and it should be in a civil manner). A thread might be needed when these two sides can't decide on one thing. A thread isn't needed for smaller changes, if one wishes to hear any opinions they can ask around, otherwise it is not necessary.

Bureaucrats are allowed to bring changes by deciding among themselves without community consensus but once again, this isn't necessary. If they want consensus before making any changes, they can. And again, non-crats are allowed to disagree with those changes, in this case, a thread may be needed. And ofcourse, everyone has to be civil.

In the case in which users think that a change requires community consensus [Normally, I think it shouldn't be too often], the amount of votes doesn't have to be measured by the number of users. Instead, by the amount of users present at the time. If, say, 5 users then 3 would be the majority vote. It can be above 50% (more than half) of the active users on the wiki. You don't have to be exact with the numbers. An estimation should be enough.
