I just straight up thought the Quincy just gave the Arrancar a Quincy Cross and taught him how to use it.

I figured that the Quincy were a little bit like the Mandalorians in the sense they can accept people with spiritual power into their culture, teach them their ways, and accept them as Quincy in name only.

The concept of blood purity can also come into this, as Echt can be as seen as actual descendants whereas Gemischt referred to half-bloods as well as those Quincy who integrated into the culture. Those integrated would be called Gemischt because they are only half Quincy in the sense they only possess the culture, but not the "blood".
