Well it's s a speculative question based on a comment from a writer.
Of which provides zero hints towards whether an imp companion would be included.
Honestly, the comment from the writer sounds more like they want to properly tie companions to the world, rather than them being essentially just PC's with a different backstory sitting around in the middle of nowhere for no apparent reason (As evidenced by the numerous "Where did X companion get abducted by the Mind Flayers from?" threads and questions)
I think that gives grounds to speculate as well as talk about how people might feel about the suggestion, as well as other ways people might expect or want to see diversity in companions in the new game.
Except that the thread was based on "Are we going to see and imp companion?" not "What kind of companion diversity would you like to see?"
Discussing beyond the scope of the notion of if a singular employee's comment could suggest the inclusion of an imp companion could be seen as off-topic discussion.
Much in the same way Astarion discussions in anything tangentially related to his existence are moderated as off-topic and directed towards targeted threads specifically about discussing him.
The comment that they think they have room to get away from the saminiess of many of the BG3 cast - who had similar backgrounds and motivations, and a bit too much overlap in race representation - is a positive one as far as I'm concerned.
I mean... It doesn't really mean anything. Yes, they have room to further diversify the cast. But will they? To what extent? Who's to say.
Especially this early on, when they haven't finalized much about the game. I mean, just look at Helia, the halfling werewolf companion they mostly developed and then cut from BG3.
It's interesting that diversity is a point at least this person keeps in mind. But the actual tangible effect it will have is yet to be seen.
I'm at least hopeful due to the fact that Original Sin 2 was pretty good in terms of diversity, as well as game interactions. But we'll have to see, we don't really know what direction they're wanting to move in post BG3 - Whether they still want to follow the popularity of mainstream audiences and gooners, or whether they want to go back to a more niche style where the emphasis is on a deeper and more interesting experience.
I think BG3 did a decent job with a number of the companions escaping the trap some games fall into, which is that they just have minor level interactions with each other and then a rather straightforward "personal quest" which is a almost a standalone experience.
Honestly... I didn't really get the feeling of them being any different to any other game, besides the roaming banter between specific companions.
The closest they came to it was a bit of crossover in the Wyll and Karlach stories.
Meanwhile, there was a distinct lack of companion reactions to anyone you meet. There were very few times when NPC's would even notice someone in your party, despite you having some rather notable potential party members (Gith are not particularly well liked. Tieflings are hated. Wyll had freaking horns. Astarion is clearly a vampire. Shadowheart is running around with a symbol of Shar on her forehead. Does anyone care in the slightest? No)
Really, I hope we get to visit cities from different factions in Divinity, so that there is more room to implement interactions with various companions. Be it kinship or bigotry. To further flesh out their role in the world and their experiences, especially if we get companions from less liked races like Orcs or Imps.
