Quite rare in practice though. Only case I have had that is gh-pages branch in a GitHub project repository, which contained only generated artifacts (generated by code in master). Which I believe there are better ways to do now. At least with Gitlab one instead uses a "pages" CI job, triggered from master, and the artifact it produces is the contents that will be hosted.
