While I understand your concerns, I have a slightly different perspective
on the statement that it "does not reflect the reality... at all."
The "About General Netlink Case" section does highlight some important
considerations for writing new netlink families, such as using helpers to
access nlattr and avoiding deprecated parsers.

However, I do acknowledge that the second best practice could be
confusing, as developers who use auto C code generation may not encounter
the issues mentioned.

Moving forward, I suggest we consider the following options:

1. Update the document to address the confusion and make it more relevant
   to the current state of Netlink development. Maybe the newly added
   section seems not enough for that. I would greatly appreciate any
   specific guidance. 
2. If the document is deemed too outdated for being kernel documentation,
   maybe I should publish it somewhere else. Do you have any
   recommendations on where it could be better suited?

Thank you for your time and consideration. Have a great weekend. :D

Lin
