It seems like somehow got overwritten to the original title of the post.
Nevertheless, knowing Apple so far, unless _some_ large-enterprise~y customer comes and objects, they will drop the support. We already know Intel support is dropping. Why not clean up rest of the things from the kernel and the userspace?
The facts: Apple put a warning in macOS 15.5 that AFP support might be dropped in the future.
The claim: AFP support will be dropped in macOS 27.
I just do not see how you get from the facts to the claim. This is just complete speculation.
