You create a new session in that server, it inherits the environment of the server. Whether that makes sense depends on if your mental model has starting a server and connecting to a server to create a new shell as distinct actions, as opposed to a singular action of connecting to a conceptually always-present persistent environment and starting a shell there. Admittedly tmux’s interface is mostly organized along the former lines, but given I prefer `tmux new -A`, my own model seems to follow the latter.
