Without CK2 level court politics systems, I'm not sure how "women intrigue" could be made a meaningful part of the game. They tried it somewhat in Rome 2, but it didn't work. The level of personal interaction just doesn't translate well to Total War as it is currently.
I'm not even sure we can blame fantasy here, because it seems to be a general pop history trend to make the exception into the rule in these regards, so we might've ended up with it regardless of if Romance mode was even a thing or not. A lot of the community seems oddly quiet about it recently (given past events). Even the Youtube comment sections have barely made mention of it.
