I got the impression that some source code adjustments should be performed
in another separate update step for this function implementation.

You propose to extend the exception handling here.
Does such information indicate a need for another tag “Fixes”?
How do you think about to increase the usage of a corresponding goto chain?

Would you become more interested in the application of scope-based resource management?
