On the other hand, having a separate Show instance for Vector Word8
would require either writing all Show instances explicitly or keeping
two separate packages.  I would prefer to have the two packages merged
into one.

But since I find a useful Show instance for ByteString useful, too, I
would go with the first variant of providing a few default instances
instead of a generic Show a => Show (Vector a) instance.  That way you
can write nicer instances for some other element types, too.  For
example I can imagine how a much nicer Vector Bool instance would look
like:

    fromBoolString "1.1..111..1"
