This is not strictly true. The release 2025-10-01 did work. Those who installed the initial release got the traditional first-boot customisation1.9.x will not apply configuration to Trixie images. That changes and those version don't know how to.
The Blog post cloud-init-on-raspberry-pi-os on 27th Nov 2025 stated
"the latest Raspberry Pi OS release based on Debian Trixie now includes cloud-init" (but was not mentioned in release notes) and had a link to the 2nd Oct 2025 Blog post
later it said "If you’ve downloaded the latest image (released on 24 November 2025), you’ll find that three new files have appeared on the boot partition"
It also stated "The legacy method still works …" (which appears to be untrue).
