-R causes a forced rebuild of *all* dependents recursively and will
cause lots of unnecessary builds. There is currently no way to tell if
an upgrade of a dependent is required.

Note also, a 'port -R upgrade outdated' could cause multiple unnecessary
rebuilds of the same port as it can be in the dependents of more than
one port.

Therefore it is not the default as your upgrades would take so much longer
