Code review comment for ~waveform/ubiquity:prepare-package

given that the intention is to drop ubiquity out of main entirely for 24.04 (either leaving it for community flavors to maintain in universe if they continue to rely on it, or dropping it from the archive), I'm uncomfortable with the introduction of new code here related to oem-config, the bit of ubiquity that we don't yet have replaced in main. What is the larger plan for superseding this bit of code in 24.04, and can we accelerate that instead?
