It might.
Asking about "traditional spanakopita" is like asking about "traditional meatloaf"
Traditional is whatever YOUR Yiayia/Grandma did!
I don't think of it as very "eggy" but but some authentic versions do have eggs as a binder (not so much that it seems like you're eating Quiche, tho! - and the one I posted looked a bit quiche-ey).
This lady's blog is one I love (she's Cypriot, and has excellent English : )
She's traditional, but still creative.

Note, she has some with eggs. She also has "nistisimi" which means Lenten/Vegan. It is VERY common to see this made as a Lenten food without cheese or eggs! There are lots of varieties that are Lenten.
Also, this lady is a famous Greek-American chef. She diverges from tradtion sometimes, but she's a very good go-to source:

Note - her version has no eggs.
AS for the little cups - lets just make 100 and split them
