Smush can be dangerous. If someone has hundreds or thousands of images and mistakenly selects resize originals, not realizing the implication, weeks or months of work can be lost.
There are several requsts for bulk restoring.
So I am not the only one.
Can you please create an update that has a REVERT function to the plugin? Especially for the oringinals. They are called originals after all. Who on earth these days cares that much about server space? HD space on hosts is obscenely cheap anymore. This is not 1997 when servers were expensive.
