For me at least, it’s more about seeing some progression and permanence, so even if I do like a good bit of chub, seeing Emmie’s capacity constantly increase and her reaching a new stage of bloat every once in a while is nearly as good and clearly more in line with your interests. Little things like a fourth temporary weight stage being added in the recent update and occasionally having her move slower are gold just because of the gradient from how she was at the start of the journey.
I think the bulk of your fans’ll be pleased as long as the intensity of the shenanigans the girls get into keeps increasing, even if extremely gradually. Not that your primary purpose for making the project should be “to please the bulk of your fans”, of course, because that’s a quick way to diverge from what allows you to enjoy what you’re creating.
