It's not used directly in a lot of places. However, it's still used in a lot of publishing toolchains as an intermediate format, usually compiled from asciidoc via asciidoctor[1]. O'Reilly books, for example, are all written in asciidoc and then run through a publishing toolchain that goes through asciidoctor to docbook, to eventually get rendered into printable formats as well as PDFs.
