Probably. Not everyone's invested enough in Trek Lit to want to follow a whole series. Many readers just want to pick up the occasional standalone adventure that piques their interest.
You also want to be faithful to the original source material.
Presumably, people who pick up a TOS book want it to be like the original TV series--which was not exactly big on "interconnectedness."
In other words, making TOS books more interconnected would make them feel less like the actual show!
