Well, it took me more than a couple of days to come with a functional skeleton.
The idea is to avoid the use of bodies' faces and edges.
Because FreeCAD makes construction geometry invisible after exiting the sketch, I have to resort to use intermediate sketches containing only construction/support lines. Until now this works with single parts and I still have to try with assemblies.

I also use a master sketch when I can, and even a master-sketch driven by a design table.
In solidworks I even often used a 3D sketch just like you but with the 3D sketch you didn't needed to make more than one sketch.
In linkstage I used a body to store the master sketch, not sure why. I also had some issues with links but after some trial and error it seems to be stable now.
Can't really show the results as it is a design I am working on for the purpose on selling in the future.

1) You can use Sketcher_External on sketches. It's better than edges because it depends only on one sketch and not a full construction.
2) Show upward sketches and hide construction.

I don't understand here the need for 'master' sketch. (They are not 'master' imho.)

You are right and I'm already doing it.
The role of the "construction sketches" is to transfer reference dots, using the "Sketcher External" command, to not parallel sketches.
