In practical industrial applications (regardless of any particular industry), is there any use for a dither module that goes along with a PWM module considering HRPWM's are available. With my limited experience I can justify using the former as it's most likely cheaper than the latter. However, this is a rather weak reason, and I was hoping someone can share their experiences/thoughts on the usefulness of dither?
My intention is to keep this question as far as possible from being opinion-based or too broad, but just to make sure – I am looking for an extended 'yes' or 'no' answer to whether a dither module may be useful in practical applications.

Lower cost is hardly a weak reason.
Using a more expensive part than necessary, without good reason, is hardly a mark of a good design, and specifying a high-res type may constrain the design in other ways (for example, forcing the designer into a vendor with inferior pricing, availability or performance).
Power consumption may be less too, though it's probably not a huge difference overall.
