I don't think the addition of cloud-init deprecates anything or creates any issues with existing tutorials.
What does concern me, is that the image I tried to customise and flash with RPi Imager yesterday to a Pi Zero 2 W, failed to perform all of the customisations and left me having to manually correct it all by finding the hardware and hookin g it up to a monitor and keyboard.
