Another downside is that Google is no longer releasing the source code for monthly security updates, only for quarterly ones. This, in conjunction with other delays in OS source code, means most custom ROMs can’t ship monthly updates anymore. Add this to the pile of other things that make it harder to mod your Android phone in 2025.

Great, Google is making AOSP-based, Google-free ROMs less secure. To accomodate corporate partners that are unable to do monthly bug fixes.
