 More quantitatively, the values of $D_0$ are within chemical accuracy (\ie, an error below $1.4$ mHa) from the cc-pVTZ basis set when using the $\pbeontXi$ and $\pbeontns$ functionals, whereas such an accuracy is not even reached at the standard MRCI+Q/cc-pVQZ level of theory. 
 
 Analyzing more carefully the performance of the different types of approximate density functionals, the results show that $\pbeontXi$ and $\pbeontns$ are very similar (the maximal difference on $D_0$ being 0.3 mHa), and that they give slightly more accurate results than $\pbeuegXi$. These findings provide two important clues on the role of the different physical ingredients used in these functionals: i) the explicit use of the on-top pair density coming from the CASSCF wave function [see Eq.~\eqref{eq:def_n2extrap}] is preferable over the use of the UEG on-top pair density [see Eq.~\eqref{eq:def_n2ueg}] which is somehow understandable, and ii) removing the dependency on any kind of spin polarization does not lead to significant loss of accuracy providing that one employs a qualitatively correct on-top pair density. The latter point is crucial as it shows that the spin polarization in density-functional approximations essentially plays the same role as the on-top pair density.
-This could have significant implications for the construction of more robust families of density-functional approximations within DFT.

+\manu{Also, we did not report the performance of the $\pbeuegns$ as the latter gave much poorer performance than the three other functionals. The essential reason for these bad performance comes from the fact the $\pbeuegns$ has no direct or indirect knowledge of the on-top pair density of the system. Therefore, it gives a correlation energy for the totally dissociated H$_{10}$ chain even if the on-top pair density is vanishing in that case, which necessary lowers the value of $D_0$. Therefore, from thereon we simply discard the  $\pbeuegns$ functional. }
 \PFL{The functional $\pbeuegns$ is not mentioned and should be discarded at this stage (and explain why).}
