In my opinion, the change of the fpc's base units to use namespaces is a
positive change. The side effect is that requires adjustment of the
existing codebase. I believe there are some approaches to address this
problem, if the fpc dev team decide to namespace base units. Maybe, unit
aliasing can be used.
