I'm not nitpicking and it's fine to be very critical.
From my POV it was either PC/mobile or PC/console expansion.
Ancestors Legacy + Iron Harvest is proof of concept, that console might work for a spin-off CoH game.
I doubt this will be a faithful sequel to CoH1/CoH2, so they have to market this differently (not CoH3).

In all honesty as other people have stated before me, I agree that Dawn of War 3 MAYBE could have worked, if it wasn't called Dawn of War 3.
So like you said, this is not a faithful sequel, while using the same name and being portrayed as such.
So again, it probably maybe would have worked as a sort of MOBA-RTS mash up if it wasn't using Dawn of War's name which is known for squad based tactical and strategic depth of combat and perhaps scale.
Most fans of the series, like me, I am guessing wanted and were expecting Dawn of War on Dawn of War 2/Company of Heroes 2's engine with DoW2's improvements and maybe some on top of those as well but that's about it, nobody expected for them to try and do mental gymnastics by trying to invent the wheel all over again. You got something good, something that was loved and has a following even until today (I still believe more people play DoW than DoW3) so you improve upon that while maybe incrementally adding something new like with DoW2, there was absolutely no need to depart so drastically from the core DoW gameplay in my opinion and I have no idea why they did it in the first place, trying to always be the best, the newest and the most "hip" almost always backfires.
Relic made history with both the first DoW and CoH because they had an idea and THQ was willing to invest into it so they tried it out and they found that it was liked and well received but I don't think imagined that it would be one of the top RTS games ever rated.
In a time of a market while not over-saturated like now with StarCraft and AoE as well as WarCraft clones they were the dominant things and DoW and CoH sorta broke that mold brilliantly which made them stand out.
So to me personally that's why they were so well done and loved, because they weren't doing it for the money or anything, they were probably content with the fact that the game might fail or that it might just get a niche following or whatever but still did, they still tried and they poured all of their love and creativity into it so that's why it worked.
And I know I'm starting to sound like a broken record here but Dawn of War 3 was made with the idea to re-invent the wheel by combining a nowadays pretty popular genre (MOBAs) and RTS which is a more niche and less popular genre and that's ironic but whatever, point is, you do it for the innovation and making something new, good and interesting, not to make a lot of money or to be popular because it will blow up in your face big time and that's where a lot of the nowadays triple A devs fail at and where the Indie devs pickup I think.
