When I was trying out the series yesterday, I was wondering if this is
something we can autodetect.

Output from "asciidoc --version" is easily machine parsable for giving
asciidoc7compatible aka ASCIIDOC8, but I couldn't come up with anything
simpler than probing a few hardcoded paths under /usr/share/sgml; that
approach is unacceptable because would not work if your stylesheets are in
somewhere we do not know about.  Ideally, we should be able to ask the
tools we invoke (e.g. xmlto) to get that information.
