It is a miss-feature.  The assumption is that failures are transient and
that the client should retry indefinitely. After all, your client might have
correct credentials and the server's configuration may be wrong. :)

You can supply a false wait option and then test yourself for a
successful connection.

There's also a timeout option, but it doesn't work as most people
would suspect.  That could easily be called a bug.
