Yes, Subgraph OS is meant to be used as a general purpose desktop operating system. There is pressure on TAILS to evolve in this direction by people who like TAILS and want to use it as their main everyday OS, but this conflicts with the 'amnesic' philosophy and vision of TAILS as an ephemeral read-only system.
