Recently, I have been reading apocryphal and pseudepigraphical texts, and like many before me, I am struck by the extremely specific similarities between 1 Enoch and the LDS's Book of Moses. I flipped to the back of the LDS's Bible Dictionary, and noticed that the LDS Church also agrees that there are many truths in 1 Enoch. I also found a fascinating article by LDS scholar Hugh Nibley pertaining to 1 Enoch.
I understand from this Q&A why other Christians do not canonize 1 Enoch.
I also understand why non-LDS folk would not find the parallels and similarities (in comparison to the Book of Moses) genuine enough for the Books of Enoch to be canonized by the LDS Church, as detailed in length in this Q&A
However, I do not understand why the LDS Church does not choose to canonize this text if they consider it be an inspired work with many truths similar to their own. What are the key aspects that make LDS authorities skeptical of fully embracing 1 Enoch as part of the sacred writ? After all, they have Songs of Solomon in their canon... 1 Enoch seems a lot more relevant and aligned with their doctrine.
they have Songs of Solomon in their cannon: Actually, "The JST states that 'the Songs of Solomon are not inspired writings.'" - lds.org/scriptures/bd/song-of-solomon?lang=eng
