Which is of no relevance to me in the first place because I watched the show and read the books for years without some artificially-induced sense of peril to substitute for suspense
Me too, mostly. But I used to hang around with 200 or so ST fans (100 or so die hards, the rest casual SF fans and relatives of diehards) every month through the 80s, at monthly TOS marathons on a big screen, and I know that I was one of the few who was reading
all of the novels as they came out. Most other fans there would boast that they had
no interest in the tie-ins because the stories "didn't really happen", and that they knew the authors weren't allowed to put the characters into impossible situations, unless they were new redshirts created by the authors, of course.
(When Paramount people first started mentioning that they knew that less than 1% of general audiences were completist collectors, I could see they were right.)
I do recall being less than impressed reading most TOS novels set in the 5YM while the movies were running, because I knew everyone would always survive. (Similarly, DC Comics were eventually told to set later comics between movies that had already screened, to lessen continuity problems.) And I remember well the huge controversy caused by Pocket's first original novel, "The Entropy Effect". Kirk was slated to die - horribly - and the cover art had the characters in their ST:TMP uniforms. It was coming out after TMP and the Kirk fans were in uproar. They remained in uproar even when "Starlog" printed a chapter of the novel, and pointed out that this adventure took place
before TMP. Then the novel came out, it was hugely successful, and author Vonda McIntyre had gained herself many more fans for her original SF.
But you can only do that kinda stuff every so often. Spock's canonical death in ST II ended up even bigger, of course, and Nimoy went into that with absolutely no intention of ever returning.
And, despite what any editor might have said about the permanence of death, you can't ever leave a good character dead in science fiction. (Unless the character stakeholders have enjoyed this endless Janeway debate so much that they keep Janeway dead to enjoy the continued publicity it generates.)
