How do I make a custom shader in "Fade" RenderMode?

The Unity5 Standard shader has a few render modes, Fade is the closest to what I want to modify/build off.
How do I set up a custom Unity5 shader to have transparency in this "Fade" style

Ultimately what I'm trying to make is a Transparent shader for hair which is considered geometry/masked by effects like DoF and also casts and receives shadows.
These are all very standard things to want out of a Transparent shader, for purposes like character hair, it's a shame Unity5 didn't come with one...

 

bump.
Why does pretty much ever thread on this forum just get ignored or replaced with a new thread about the exact same thing... where are the unity team? Why wont they help?
