Personally, I think that Sukelik was correct with an idea he floated early on in the DSS debate (back in the early 1960s, IIRC), which was that the Qumran caves were basically genizot - mortuaries for worn-out or corrupted texts. If so, this would seem to give added support to the preservation of the Masoretic text, since what would then seem to have been thrown away as corrupt in the caves would be mss. that deviated from the Masoretic, even in a few words or letters, suggesting the methodology of the Masoretes is older than scholarship currently thinks it was.
Strange idea though,,,,”shaheed, this scroll is worn out (or completely wrong) carry it FAR into the desert, miles and miles,, then find a cave where it can be safely stored”.
Strange behavior to do with their discards.
