Let’s not stir sleeping dogs. ‘FTP changes’ is a shorthand term for a bunch of stuff “technically a separate proposal” (and including reorging AMP), none of which were clearly signalled in advance; and that wiki substantially underestimates what was actually coming. (For example the wiki doesn’t mention the changes introduced a bunch of instances, that might have been contrary to instances other libraries had already written.)
Here might be a place to understand the sorry mess. (And SPJ’s attempt to ‘move forward’ a few messages later.) There’s a mix of people surprised at the suddenness/lack of notice; surprised at the decisions (some eventually persuaded they were ‘logical’); surprised at the scope/impact of what appeared in one release; as well as plain disagreeing with the decisions.
