Abstract We elaborate on the recent work of Moritz et al. where it is argued that anti‐brane uplifting in KKLT models never leads to dS vacua. This is due to flattening effects in the effective potential found when treating the gaugino condensate energy momentum in ten‐dimensional supergravity. We point out that the Silverstein‐Saltman uplift, which effectively dissolves the anti‐brane in 3‐form fluxes, is a conceptually simpler setting in which flattening effects can be present, without requiring assumptions about UV/IR mixings. Along the way we revise and improve on the arguments of Moritz et al. and discuss various subleties when studying gaugino condensates from a ten‐dimensional point‐of‐view. In particular, the “no dS” argument is slightly weaker and we emphasize a technical loophole that might allow dS vacua. Finally we suggest that AdS vacua which are parametrically controlled from these flattening effects belong to the Swampland. We comment on the relation with the recent refined dS Swampland inequalities.
