Hi It would also be nice, if like R, one could run a system-wide install for users (e.g. in a university lab environment) and users could have optional packages either installed system-wide, or locally (e.g. .sage), and that those packages gracefully stated their minimum sage version to work on, or gracefully (in some sense) declined to work when there was a mismatch.
