On an Eagle board with a KiCad schematic, board_update lists 23 parts as unsupported pad_net_change, but every one is a rename: X1B vs /X1B, 0/TX0 vs 0{slash}TX0 from kicad-cli's escape, and N$9 vs Net-(J5-CC1). The ask is a rename mode when pad sets map one to one, as KiCad's Update PCB from Schematic does; the workaround is a board-local fix_pcb.py.
