Yes, that is another alternative. At the moment we're all theorising about this it's going to work, but until we can get empirical and start testing some actual code, we aren't going to be drawing any firm conclusions. I think etcupdate(8) has a longer history and people are more familiar with it whereas the 3-way merge code in pkg(8) has been exercised relatively rarely. There's also considerations about how this would fit into various different workflows -- everything from people that only ever download the standard pre-compiled packages for a release, to developers trying to cross-build highly customized embedded systems. Having a 'merge' step that is separated from the 'install' step seems advantageous in that it allows a point where people can substitute in their own alternatives for managing /etc files.
