Besides getting some attention, pretty pointless. If a tech-savvy company is truly into serving static files, they wouldn't be using WordPress in the first place. If a non-tech-savvy company is building a website, they don't know what any of this means.

In any regard, this has already been possible for some years by simply going into CloudFlare Page Rules and setting up "cache all" across your entire domain, effectively turning WordPress into a static site that is served purely from their CDN edge locations (100% free).
