A consensus? I think probably not. :)
I like the idea that the date datatype performs validation on the values entered. I personally would create a date field with a before insert/update trigger that sets :new.date := trunc (:new.date, 'MM') ;
If you need an index on year then you can use a function based index on trunc (date, 'YYYY')
