I've often wondered if the infamous Google banners about "you should really be using Chrome for our websites" should be considered a form of this.
Suspecting that them only requesting it, rather than mandating it (in the message) might stop it crossing the threshold. Even though there (at least used to be) plenty of cases where (say) Firefox would outright not work properly with Gmail, so Chrome or a derivative had to be used.
