> I have some wariness that its widespread use could actually have a shaping, and, specifically homogenizing, effect on language.

This could be a benefit in industries where the goal is to have homogenous writing that meets a given set of specifications/standards. Some ideas:

1. Peer-reviewed scientific writing and/or abstracts

2. Manuals

3. Materials written for a subset of language (EFL, pidgin, children's books)

4. Documentation
