I dare to point change possibilities out which correspond to a special error category.
There can be different opinions about their relevance for further software improvements.

Do you know the run time characteristics for the discussed functions good enough?

I suggest a bit of code reduction at various places once more.

I sent update suggestions in this scale since the year 2014.

I agree that the corresponding number could be remarkable.
But there are also other source code search patterns involved besides information
around these logging functions.

You are right that some agreements and disagreements were expressed already
(depending on the software area).
