There is no way to reference a specific quote on Wikiquote.

Why and when would anyone want to "reference a specific quote on Wikiquote"? Use case welcome.
You can provide a permanent link to any revision of a page or a section. If you want to reference (in a scientific sense) a specific quote then you'd need to reference the original source of that quote, and the original source is never Wikiquote.
