I don’t think that’s the case because ‘guix publish’ creates narinfos and nars atomically (see ‘bake-narinfo+nar’ and ‘compress-nar’). That is, the worst that can happen is that the rsync client copies temporary files corresponding to incomplete nars or narinfos, but these files are not going to be served. Thanks, Ludo’.
