Well, It is bad because server (client) can cache ip address for long time and then one of your smtp server fails. It can take long time before server gets ip address of working smtp server..
The client is faulty in that case. If it fails to contact the server it first tries it should then try a different one. And a client which won't retry when it can't reach a server will have exactly the same problem even with normal MX records, as it won't fall back to the lower priority records if the primary is offline.
