 want to „recover“ from stuff like missing one of the python library files
 or .so files for C++ applications. In which way is this different?

 top-level python program, store the backtrace somewhere and put a fatal
 error into log?

 That can be a solution.  My point is not to leak the exception up to
 the interpreter level this way.  There may even be a case where we
 allow that - missing a critical python module on import, probably
 because of installation error, could be one such case.  But I don't
 think it applies to this case.  IMO it should be at least caught at
 the top level, and may even have to not be considered fatal.
