For context, as mentioned the appID in Touch was <pkgname>.<appname>.<revision>. The concept of appID lives on in snappy as snap.$SNAP.<command>. If the goal is to construct anything yourself, the new env var probably shouldn't be SNAP_APP or SNAP_COMMAND since both imply (to me anyway) '<command>' or '$SNAP.<command>'.
