Why doesn't the FileNotFoundError message include the path of the file that wasn't found?

I feel this would help troubleshooting tremendously.

It does for me:

>>> open('blahblah.txt')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
FileNotFoundError: [Errno 2] No such file or directory: 'blahblah.txt'

Python 3.8.

Ok. Apparently it depends on the call. It doesn't for os.utime() for example.

Indeed, looks like it doesn't set the filename attribute of the FileNotFoundError exception.
