What Is Devourer's Intended Use Case?

With the way that Devourer works right now, it's objectively stronger than every other jungle enchantment in the game once it's sated, and anyone with even moderate on-hit synergy can abuse it pretty easily. My question is 'is there a healthy use case for Devourer'?

Ezreal is perhaps the quintessential item abuser: even in the year and a half since I've been playing League, Runeglaive, Rageblade, and Iceborn have all been nerfed, either directly or indirectly, because of Ezreal. What makes those items different than Devourer, though, is that there are other champions who use them in a healthy way. Nidalee, Kayle, and Poppy all have good synergy with those items without abusing them, for example. Devourer doesn't have that structure: either it's useless (Nidalee) or abusive (Jax).
