--failnode is actually very similar to --param="failover.node=".
In both cases, the same parameter (i.e. PARAM_FAILNODE="failover.node=") is
stored in the configuration logs. The only difference is that --failnode
enables MMP automatically, that's why we recommend to use it.
To sum up, there should not be any compatibility issue (BTW, --failnode is
also available in 1.6, AFAIK).
