This scenario is based on swampland conjectures, that lead to the relation $\\rho_{\\rm swamp}\\sim m_{_{\\rm KK}}^4$ between the vacuum energy $\\rho_{\\rm swamp}$ and the size of the extra dimension $m_{_{\\rm KK}}^{-1}$ ($m_{_{\\rm KK}}$ is the mass scale of a Kaluza-Klein tower), and on the corresponding result $\\rho_{_{\\rm EFT}}$ from the EFT limit.
