I got curious and tried this myself.

I couldn't trigger "unsafe" error.

Here are randomly selected differences between the documentation pages formatted with AsciiDoc 7 and 8.

I haven't dug into the list archive article I quoted yet (the pointer is also found in TODO file in 'todo' branch) and haven't tried the backward compatibility pragma, but you can clearly see that the above differences are simply unacceptable. They are not insignificant cosmetic differences -- the most important techinical details are being mangled, rendering the documentation useless. We _do_ need the backward compatiblity enabled in asciidoc.conf or somewhere.
