That's a simpler definition of schematic and that's fine for you to use that flow,
completely separating layout from anything you consider in detail, letting
someone else or an autorouter handle that.

Make definitions of trace width quickly on a schematic by select-and-add-attributes,
so an autorouter can run to completion with medium current handling traces
routed DRC close to each other and other traces.

In your work flow, English words convey duties to hired layout persons.
In my example, I only hire the autorouter.

Sounds very useful.  Especially for open hardware projects and hobbyists,
and bottom line oriented business folk.

What I called select-and-add-attributes is an imaginary function not existing in gschem.
Yet...
