Legal Documents is the big one here. I do think the philosophical notion is kinda cool and interesting, although I am too much of a hoarder to ever use this.

But legal document fading away just because you Haven look that them is just invitation for governments to fuck you over. Just a simple example in Germany taxation. If you do your own tax report then you usually do that 2 years after. So this year I did my taxes for 2023. Now the problem is with this OS all my data and receipts bills whatever that I have to send to the government for my tax report would be gone because why would I open it before I need it.
