I'd agree if all Imperial planets were alike, but they're not. Using rough riders can help theme your army to be a more barbaric one or, in the case of the Death Korp, one that resembles a WW1 army etc. Also rough riders dont neccessarily have to be mounted on horses, you could mount them on giant lizards (storm troopers on tatooine anybody?) or even give them combat bikes using the rules for rough riders.
All in all I think rough riders are a great idea and in keeping with much of the Imperial Guard background- the 'if it works why change it?' philosophy.
