Why are FileObject commit errors handled silently?

When using FileObjects:

file = FileObject(
    backend="s3_nonexistent",
    filename="test.png",
    content=pil_image.tobytes(),
)
image = Image(
    height=100,
    width=100,
    channels=3,
    file=file,
)
session.add(image)
session.commit() # <- will not fail even though the s3 bucket did not exist and the file upload failed

The commit will be succesfull, only later on file.get_contents() will it become clear that the save operation failed. Looking at the code it seems that this is caused by suppressing all exceptions and only doing the checks in the after_commit listener.
I was wondering what the design choices were behind this and if it is not better to do things in before_commit and let all exceptions through.
