Built-in overhang

I'm finding painted aluminum drip edge at Lowes with a profile that extends out from the roof surface then angles back toward the fascia. It looks like it will provide a built-in overhang. Called a T-style drip edge.

Shop Union Corrugating Galvanized Steel Drip Edge at Lowes.com

Seems like it's an improvement over having the shingles overhang by themselves with no support.

Should I use this stuff or is it for some specialized purpose, and if so should the shingles extend past the drip edge angle, or only out to it?

That profile of drip edge would be fine for a gable end or for a flat roof. But you would probably not use it above a gutter as it looks like it's a 90 profile... not bent at a pitch.

Below the first course of shingles you should look for gutter apron, which will look almost exactly like that, but it's bent at about a 20 angle so that the gutter can more easily slip behind it.

Gutter behind it? All the drip edges I'm seeing have a less than 90 degree bend, but back toward the fascia so it presses tight against the fascia.

Not sure what you mean but I'll look for a gutter apron.

The starter strip and shingles hang out past the edge of the drip cap by about 1/2".

. . . but it's bent at about a 20 angle so that the gutter can more easily slip behind it.
I guess I'm not seeing the problem. My fascia is 90 degrees to roof slope so it tilts inward toward the house. Bottom is about an inch directly over gutters. So drip edge is directly over the gutter.
