I will note that the suffix "-ín" in Irish is a diminutive just like "-kin" in English
So on a semantic level the appropriateness is more equivalent than you might think!

Although in "puimcín" that "-ín" isn't functioning as a diminutive (it's like the "-ín" in "cailín")

What do you mean?
The "-ín" in Cailín is definitely diminutive. Compare cailleach "old woman" with cailín "young woman"

I think what you mean is that without the "-ín" it is not a stand-alone word, right?
That is definitely true. "puimp" or "pump" are not Irish words. In fact, "puimpcín" is also not a real Irish word. Pumpkins are not from Ireland, as we all know. But then again. Neither are potatoes!
