Cool! I'll do some reading. Might make for a good project next time I'm on vacation.
(Of course, keeping hardware in use even as software requirements increase is kind of a hard problem; Debian itself used to have its own projects - Emdebian 'Grip' and 'Crush' - to try and address that issue with a broadly Alpine- or pmOS-like approach, but these were abandoned a long time ago unfortunately. The whole "embedded" Linux space is a bit of a mess, and a broad, community-led project like Debian could have a positive impact there.)
