Avoid splat (...) operator for keywords arguments?

Performance tips

• Avoid the splat ( ... ) operator for keyword arguments.

However, from official Julia guide:

https://docs.julialang.org/en/v1/manual/performance-tips/index.html

I dont find this * Avoid the splat ( ... ) operator for keyword arguments.

Question:

• Is the official manual’s Performance Tip missing this trick?
• May I know some example of such splat for keyword argument, and Why it is better to avoid them?

Thank you
