Hi. Thinking one moment from my POV. I have never been asked by a client to install a WordPress site. Those clients that I have worked for have been in 2 camps. One (most common) already have WordPress and are most concerned to keep the data in the database and the ease of use of the backend, but want totally different front end and often additional functionality. Whilst they will not see that I might use the WP REST API, my doing so will not impact negatively on their needs. The other set of customers have a need for an all new site, no legacy required. WP REST API will not impact negatively on that either. Does WordPress NEED a public image and branding, that is, for the users of the website? How many people visiting a website realize they are visiting a WordPress powered website, or even care? Will WordPress become irrelevant? I doubt it.
