awesome-security-hardening VS privacy-respecting

If you want to go extreme, I remember from many years ago, there used to be a publicly released document by Australia's cyber security agency, made largely for Windows, which used to list attack vectors on a complex scale. I used to follow their listed possible vectors to formulate threat models as a kid for my Windows computer. Back in the day they used to provide PDF, now its webpages (https://www.cyber.gov.au/acsc/view-all-content/advice/guidelines-system-hardening). This also exists (https://github.com/decalage2/awesome-security-hardening), a bit more wide coverage of OSes and practices.
