+With several stored accounts (see `sentry auth list`), `sentry org list` lists
+the organizations of every logged-in account together, each fetched with that
+account's own credentials on its own server, plus an `ACCOUNT` column. An
+organization reachable from several accounts on the same server is listed once,
+under the active account if it is one of them, else the most recently used.
+Accounts whose login fails are skipped with a warning. `SENTRY_HOST`/`SENTRY_URL` limits the list to accounts on that server,
+and `--account` to a single account. The stored active account never changes.
