I have the strong impression that the current fleet of LLVs are, at this point, each an individual work of patchwork art, still moving only due to the constant attention of dedicated genius grade mechanics. But that would not be possible had they not been built, intentionally, with some of the most common and vanilla parts available.

A new fleet that uses parts nothing else does will be an expensive boondoggle destined for quick sale as surplus.
