Well, that doesn't make any sense. Pocket Trek has never been limited to publishing tales in only one all-encompassing continuity. Even during the current era when there's one primary novel continuity, there have still been other books that stood apart from it, like the Shatner novels, the Crucible
trilogy, and The Children of Kings
. Cross Cult has already published Crucible
, not to mention translations of the 2009 movie novelization and a couple of the Abramsverse Starfleet Academy
books. They haven't limited themselves to a single book continuity in the past, so why start now?
Probably because they number their books and have IFM planned as number 7 in the TNG series. Since the feedback is mostly that they should publish it anyway, just outside the main (=numbered) TNG series, I guess that is what will happen.
I don't really get why the number the books anyway, but they still cling to call DS9 Relaunch Season 8 of DS9, and promote/number Warpath as start of Season 9, so they probably just have some kind of fetish for numbers.
