Beeline always exits with fixed code

Beeline process internally knows when there was a connection error, what type of connection error (i.e. timed out, already open, etc. Beeline#handleSQLException()) or error while running query. When running a script via beeline, in case of any error the exit code is always 2.

I wish to handle each error in different way from an external script and needed the Beeline to return different codes when it knows exactly what the error is. Should I return error codes like 10, 11, 12, ... ?
