Eyebrow Shape and Hair Body Parts - Why?

Does it make any sense that an avatar's eyebrow shape is a part of the hair you're wearing? Intuitively, one would expect it to be contained in the body shape, perhaps in the eyes section.

This is particularly annoying when going through different hairstyles or attachments (as most prim hair also makes use of an included SL hair part). Every time I try on some new hair, it's as if the hair has taken over my avatar's brain, and the eyebrows suddenly jump up into all sorts of weird, distorted configurations.

Explain.

Happens to me too with the lot of hair I've worn. It's puzzling, like how there is no neck attachment slot. I don't know of changes going to be made to this, but the counterpoint I've heard since '04 is that eyebrows are hair, so eyebrow shape directly correlates with that.

The way you phrased that is great tho, Tyken.
