Outdated Documentation: All sync calls in favour of async calls

The whole documentation according to "All sync calls in favour of async calls" is outdated since v108.0.0.
A lot of sync calls are back :) (except streaming json? #1800 #1797 )

I removed that line from the docs.

I don't know what you mean by "the whole documentation is outdated". I have no plans to add examples for sync overloads as they are exactly the same, and just wrap async functions.
