In DevHub (https://developer.wordpress.org/), we have Code Reference, Theme developer handbook, Plugin developer handbook, etc. but some topics are independent from those categories and quite common. For example,
- Latest Programming Topics in make core (e.g. Security in 5.2)
- Security
- I18N
- Error handling
- Debug Technique
- API usage (e.g. https://codex.wordpress.org/Settings_API)
- License
- etc.
What about creating the “WordPress Developer Handbook” for these common topics?
