For a given core nucleus, the resulting (K) over bar separation energy B-(K) over bar, as well as the associated nuclear and (K) over bar -meson densities, saturate with the number kappa of (K) over bar mesons for kappa>kappa(sat)similar to 10. Saturation appears robust against a wide range of variations, including the RMF nuclear model used and the type of boson fields mediating the strong interactions. Because B-(K) over bar generally does not exceed 200 MeV, it is argued that multi-(K) over bar nuclei do not compete with multihyperonic nuclei in providing the ground state of strange hadronic configurations and that kaon condensation is unlikely to occur in strong-interaction self-bound strange hadronic matter.
