It seems that this case did not happen for me so far if you are looking
for this exact source code search pattern.
Variants of the current pattern were occasionally discussed a bit.

A few similar update suggestions are still in development waiting queues.

Partly. - My interpretation of similar changes was eventually too broad
in my previous answer.

I am proposing a change which was described also around various other
functions in some software already.

I got the impression that special software development habits can also
evolve over time.

I am trying to increase the software development attention on error
detection and corresponding exception handling at various places.

Do response times for system failures matter here?
