No [IMHO]. This adds something unconventional and complicates things. There
should be no difference in the output form. It should be quite obvious that a
dimension or unit output is reduced or not. Plus, there are dimensions whose
reduced dimension is identical to the dimension. The user can also explicitly
ask for a reduced dimension through functions such as reduce(identifier).
Reduced dimension can have reduced units (why not)?
