The spinoffs have never had the leeway the main show has with Hasbro, as though the best IDW could get from them is a “Yes” or “No” answer along with set parameters as to what a character can and cannot do, a “show bible” so to speak. IIRC someone at DHX acts as a direct line and liaison with Hasbro so they have much
quicker responses. Wouldn’t be surprising to know down the line that the staff at IDW stopped asking and just went with the safest options there are, mainly to follow comic-only storylines (Nightmare Forces, alternate dimensions…)and not bother with anything too creative. Plus as horrendous as Seige was, it still must’ve been at least frustrating to see their work obliterated like that.
Same with Starlight, they got the memo from S6-7 Hasbro that their
version isn’t allowed to be flawed in any way, so they just stopped caring after cramming through the Accord arc. ¯*(ツ)*/¯
Would be nice to see the comics and maybe even EQG have a second take on her S8-9 self before they end, too.
