Here we have a type check (instance?), which may not be clean.
To change IConnection may be cleaner, but that may bring compatible
issues(support the user already implemented some messaging with current
IConnection declaration)
If the messaging connection has extended ConnectionWithStatus, then we will
check the status.
If the messaging connection has NOT extended ConnectionWithStatus, then we
behavior in the same as before. (We will skip this check)
