(Make sure you pick .dummy so as not to interfere with any other DNS.)
In theory you could leave off .dummy, but then you risk hostname being completed with the search domain in resolv.conf, which creates the problems already mentioned with putting hostname.domain.com in /etc/hosts. (I have not tested this at all!)
I will probably just leave this decision to the application architects, with the recommendation that we should simply use DNS as intended...
