So on the grand scheme of things, someone out there is definitely holding on to them so no harm no foul. That being said, what the guy at the top comment implied is that 8GB is such a small amount of space that you shouldn’t even have to “worry” about keeping it, just keep it because its so small it won’t do you no harm to have it around.

Or dump it into data hoarders and let someone else take the storing burden.
