At my PPoE, if the components were assembled on the PCB, that's the way it was done. If they were connected to something (screw grounded), that connection was shown, too. If the parts were assembled at a later time, then the parts are shown at the higher level assembly.
It depends at what level they're assembled (and perhaps inventoried), IMO.

having a PCB symbol on the schematic also handles when the PCB outline and screw holes are made by the guy doing mechanics, that then become the "foot print" for the PCB symbol
also means you can automatically update your parts inventory extracting the parts used
The mechanical guys don't do touch the PCB at the CPoE. They send a CAD drawing to the layout guy. At the PPoE, it was much the same. I put some mechanical components on the board but only when it made sense. Usually the BOM chain is left to the manufacturing engineer. They decide what order to build and what level of parts to inventory.
Yes, but as long as everything is on a BOM, at some level, it all works out. The question is how it gets there. I'm all in favor of putting everything on the schematic that gets assembled and inventoried at the board level. I guess it's simpler to say that I want everything on the schematic that I'm responsible for. If it's a higher level of assembly, let someone else worry about it. ;-)
