For example, if the transform is set to scale the image by a value near MAX_INT(AffineTransform.getScaleInstance(Integer.MAX_VALUE, 1)), is it really good thing to return an image of the original size with "corrupted" content? In what cases it might be useful?

There isn't corrupted content, it is partial content in the case of an image that is too large.
And this seems far more useful and friendly than the exception.
What you are raising is no more than what I called out in the description at the very beginning of this PR some 2 months ago.
