Like I said, I kinda get it. But for me the utility of the adjustment far outweighs any concern about them coming loose. They'd have to loosen at both ends for the barrel to turn. And even then you still have the nut on the other side of the LCA. Not to mention if the length of the strut rod changed more than slightly it would start pushing or pulling against the LCA. Honestly the kind with the single through bolt at the LCA has more of a chance of coming loose, and if it does then the strut rod is totally free.
A drop of blue loctite and away you go
