rpcbind.* is enabled in 90-default.preset. rpcbind listens globally, but it is not useful without explicit configuration. Please consider removing it from the preset.
rpcbind doesn't require any configuration by itself. Other services which use rpc information might, but probably not all. rpcbind has an explicit exception in http://fedoraproject.org/wiki/Starting_services_by_default. I think this is reasoanble compromise, and it should continue to be enabled by default in the presets.
Under the current presets, installing libvirt causes rpcbind to open a listening socket, despite the fact that it's not doing anything useful. I think this is a problem. Unless I hear otherwise, I'll file a FESCo ticket asking for the exception to be removed.

I am also pretty sure it should stay on. But anyway, let's close this here, there's no point in tracking this at FESCO and here. If FESCO comes to a decision and decides to turn it off, then please reopen this here.
FESCo has decided to turn rpcbind off in https://fedorahosted.org/fesco/ticket/1310#comment:13 , please update the presets.
