The only downside is that a virtual node name may replace the actual host name.

However, post 5.3 SP1 upgrade we now find the old format results in NOTHING discovered. Instead, testing has shown that using ONLY the {dnsname} in the hosts file works. Moreover, using the old format appears to work (viewing log results of each nodes' identification), however a search for any newly discovered node yields no results. The fix...for now at least...use ONLY the dnsname. (Using ONLY IP address MAY also work, but have not tried that yet).
