It would be dirty. It breaks the unix mentality by integrating too
much stuff into one program and violates the otherwise clean symmetry
we are going for in workflow.

Forward the flow is
gschem -> sch file -> gnetlist -> netlist file -> pcb
gschem -> sch file -> gsch2pcb -> pcb file -> pcb

the reverse should be something like
pcb -> pcb file -> pcb2netlist -> netlist file -> netlist2gsch -> sch
file -> gschem
pcb -> pcb file -> pcb2sch -> sch file -> gschem

See how each tool only does on step. That is one of the principles
that make gEDA great. Integrating more stuff into one program is more
like what kicad would do.

Sorry I am still opposed here. If back annotation excites people
though I could work on that. It kind of flows with my current plans
anyway.
