      Are byte/short optimizations useful on "Microsoft Word" applications?
      I can't say for sure, but I've seen (and written) code that benefits
      from coalescing memory and ALU operations, and that sometimes includes
      irregular computations.


These "vector byte" operations show up in image processing code, where
every pixel is a byte.
