I agree. No, wait, I don't agree. "Why?" you say..? Because specific examples show that this is disjoint among different seed worlds.
Example 1:
Seed 274966093
Map Level 0/4 = center point at 0,0 with NW corner at -64,-64
Map Level 1/4 = center point at 0,0 with NW corner at -128,-128
Etc., just as you describe above...
HOWEVER,
Example 2:
Seed 1633530955
Map Level 0/4 = center point at 0,0 with NW corner at -64, -64
Map Level 1/4 = center point at 64,64 with NW corner STILL at -64,-64
Etc., with center point moving farther and farther SE, with each map anchored NW at -64,-64
Another example of what should be happening:
Example 3:
Seed -779297878
Map Level 0/4 = center point at 0,0 with NW corner anchored at -64, -64
Map Level 1/4 = center point at 64,64 with NW corner STILL anchored at -64,-64
Etc., with center point moving farther and farther SE, with each map anchored NW at -64,-64

At the bottom of the page in the images, image MapZooms.png shows the OLD way of mapping, what you are describing above. Image Map18Zooms.png shows the NEW way of mapping, what we are expecting now.
However, since we have 3 examples showing how mapping is not working consistently across all spawned worlds, that is the reason this ticket was raised, and our frustration for the ticket being closed/resolved as "working as expected". It clearly is NOT working as expected in every case.
I encourage everyone to review my findings and elaborate on any other concrete examples of map zooming issues.
I agree - it is not official. But when different worlds display different behaviors for map zooming, then something is broken.
As noted in this example, World Seed 274966093 will zoom maps with everything instance having 0,0 at center. However, World Seed 1633530955 will zoom maps with every instance using -64,-64 as the top left anchor point, and changing the center as described in the Wiki.
Please explain why there are 2 possible map zooming algorithms with no way of knowing how maps are going to work in any specific World Seed occurrence? What is Mojang's official report on how maps are supposed to operate? Where is the link to the appropriate documentation?
Was this ever officially announced as a feature change??
This is NOT WORKING AS EXPECTED. Every WIKI post reports that Map zooming should all anchor top left to the -64,-64 coordinates.
I gave support everything they could possibly need to reproduce the error, and I was ignored for a false validation that was closed 8 months ago.
This ticket was closed incorrectly. I will continue to reopen tickets until this gets an honest answer or gets due attention and appropriate comment.
What was the resolution?! Admins shut this down as being resolved with no comment update, along with shutting down every other ticket that mentioned this issue.
How could this be resolved on ticket MCP-45919 in February, and this user just opened the ticket in June. You are not even following up on the examples given!
