Rust is planned to be a requirement for 3.0 (IIUC), but I don’t have any recollection of the proposed timeline.

As you said above, what was reported is totally expected (I understand that 2.55 built properly for the OP with "make NO_RUST=NoThanks" set). I do not know why nobody complained, but we have been carrying this incomplete sentence in the release notes forever X-<.
