  It was shown in arXiv:1808.09428 that the modified 4d version of the KKLT
model proposed in arXiv:1707.08678 is inconsistent for large values of the
parameter $c$ advocated in arXiv:1707.08678, since there is a point in the
moduli space where $|D_SW|^2$ vanishes. The authors responded with yet another
modification of the 4d KKLT model arXiv:1809.06618. However, for large $c$,
this model suffers from an even worse problem: not only is there a point in the
moduli space where $|D_SW|^2$ vanishes, there is also a region in the moduli
space where $|D_SW|^2$ is negative. Meanwhile for small $c$ these models have
dS vacua. We construct improved models, which are fully consistent for all
values of parameters, just as the original version of the KKLT model using a
nilpotent superfield. These models have a family of dS vacua for a broad range
of parameter values. Thus, the results of the analysis of all presently
available consistent generalizations of the 4d KKLT model, in the domain of
their validity, confirm the existence of dS vacua in the KKLT scenario.
