Seems I remember a test where some guy soaked primers in WD-40 and they all went bang...

I would be that guy, or one or em',........ALL Of them sat in WD40 for a weekend,....submerged,....they were then drained on paper shop towel, loaded and fired.
I WOULD be concerned with ACIDS inevitably present in a basement flood destabilizing priming compounds though, and perhaps tipping there sensitivity threshold in the wrong direction.
