Fairphone has the same issue for me: 5 major Android upgrades, but a new model every two years. Meaning that I can only get support until 2028 for my new phone

Same with HMD Fusion: repairing is good (and should be by design for every device), but what if the software is outdated (including security issues)?

Even customising these resources could not be enough. A good solution could be to propose an easy way to extend the generated bicep?
