There's a tug-of-war between not specifying things that aren't used
and providing basic support and/or guidance to future uses of cgen.
Just because some attribute of an architecture isn't used by current
applications of cgen is _not_ a priori reason enough to not specify it.
In this case I think the presence of word-bitsize is useful.
