I mean without that, as a reader of the code who doesn't know details, I'd
definitely be questioning why a closeable object (ImageReader) is being
obtained and used, but not closed. I probably even added it because I'd had to
dig around the code to understand that it was actually correct to not close it
here.
Perhaps the docs for SystemImage (currently `Holder class for the ImageReader.`
could be improved to make the lifecycle clear and benefit all callers of
`reader()` ?)
