The self-referential continuity of the early JNT era (up to the cancellation crisis) is Levine's legacy. Levine encouraged JNT to bring back as many old monsters and characters as possible, with "Attack of the Cybermen" (which Levine may or may not have cowritten, depending upon who is telling the story) as the high point.
I don't see how that's damaging, though. If anything, the original DW was a series that generally had too little continuity or memory of its past. I'd say that acknowledging that history was a good thing overall.
Perhaps. But I imagine that Pocket would have been happier and Star Trek novels would have sold better if fans hadn't been told repeatedly that the books didn't count.
In other words, Richard Arnold encouraged fans not to spend their money on the tie-ins.
tie-ins don't "count" as part of the core continuity. That's historically been the norm, not the exception. Heck, in past decades, tie-ins were frequently very unfaithful to the continuities they tied into or interpreted them in alternative ways, like Ashley McConnell's eccentric take on Quantum Leap
(which was actually more interesting in some ways than the show itself) or the various incompatible tie-ins to The Prisoner
And it's only in recent years, well after the Arnold era ended, that we've begun to see tie-ins that were treated as canonical or pseudo-canonical, like the Del Rey Babylon 5
novels, the Buffyverse and other Whedon comics, and the like.
I'll go this far: Arnold's attitude did help promote the false belief that canon is some sort of value judgment or stamp of approval, that being out of continuity makes a story "wrong" rather than just an alternative take on an imaginary concept. I'll grant that that may have hurt the perception of tie-ins that don't "fit" the continuity. But Arnold didn't create the idea of tie-ins being apart from canon; he just stigmatized it.
