The question of the competition between $\Lambda$ and $\Xi^{0,-}$ in theground-state of multi-strange hypernuclei is addressed within anon-relativistic density functional approach, partially constrained byab-initio calculations and experimental data. The exploration of the nuclearchart for $10<Z<120$ as a function of the strangeness number is performed byadding hyperons to a nuclear core imposing either conserved total charge $Q$ orconserved proton number $Z$. We find that almost all $\Lambda$ hypernucleipresent an instability with respect to the strong interaction decay of$\Lambda$ towards $\Xi^{0,-}$ and that most of the instabilities generates$\Xi^-$ (resp. $\Xi^0$) in the case of conserved total charge $Q$ (resp. protonnumber $Z$). The strangeness number at which the first $\Xi^{0,-}$ appear isgenerally lower for configurations explored in the case of conserved $Q$compared to the case of conserved $Z$, and corresponds to the crossing betweenthe $\Lambda$ and the neutron or proton chemical potentials. About two to threehundred thousands pure $\Lambda$ hypernuclei may exist before the onset of$\Xi^{0,-}$. The largest uncertainty comes from the unknown $\Lambda\Xi$interaction, since the $N\Lambda$ and the $N\Xi$ ones can be constrained by afew experimental data. The uncertainty on the $\Lambda\Xi$ interaction canstill modify the previous estimation by 30-40\%, while the impact of theunknown $\Xi\Xi$ interaction is very weak.
