If we have a Sims 5, should seasons, vacations, and pets be in the base game, instead of in a pack?

I'ld love that, but it doesn't sound probable imo... those are three of the most profitable dlc's the game has. To offer this content in base game, the game's business plan must be remodelled. I wouldn't say that it'ld imposible to do, but i would def fear for it...
