The official term is "strategic laziness."
Acornbearer is just an example, other cards like Mistress of Mixtures or Crystal Power might be more common to be seen in slower decks.
I actually think that Acornbearer is a great card in slower decks cause it's three 1cost cards in one, while worse then other 1cost cards it's great for decks with few slots for curving out, and filling the curve with 1/1's here and there is nice. It's just awkward with effects like Jepetto Joybuzz' battlecry though.Especially for Healdruid relevant is Crystallizer, that's a good 1drop because it also enables you to activate heal synergies against decks where that's relevant (Control Warrior mostly, or for the first 5 heal to activate the Crystal Stag battlecry in not-aggressive board-centric matchups, typically midrange)
