I would appreciate if such return value ignorance can be avoided.

I find this information questionable. I get the impression from one of your
articles that you know also alternative approaches.

Yes, of course!   ;-)

How do think about to forward the error code to a log message for a file like
"stderr" eventually?
Would you like to call the function "abort" if a function call like
"pthread_mutex_destroy" failed?

Is the completion of error detection and corresponding exception handling an
open issue also in the affected wrapper implementation?
