Dear Sir:

Yet another reason why it is good to have  'Automatically write changes into XMP' ON, apart form using them with FastRawViewer - those files add a layer of protection against Lr catalog crashes, moving files to another drive or computer, etc.

If Lightroom ever crashes, or your catalog is corrupted, or misplaced, or unavailable -- all the work on settings you did is still saved into those xmp side car files. So all you’ll need to do is reimport those files back into Lightroom and you’ll have back all the adjustments you made.
