Then why not protect all other upgrade operations with a -f | --force flag, 
except when upgrading everything? It seems much too easy at the moment to 
perform an upgrade operation that has a good chance of leading to an 
inconsistent state.

To me, it feels like the MacPorts documentation is misleading the end user to

reason behind these design decisions?

I suspect you are reading experience with something like yum or apt-get into a 
ports-based system. MacPorts gets most of its behavior from BSD ports/pkgsrc, 
and the documentation tends to assume that you are familiar with that.
