Not every back-end has a concept of "head" (think about Markdown
back-end). We don't need a general concept for something that isn't
general.
Also, completely unifying every back-end is close to impossible, unless
the same person writes every back-end[1]. Most of the options are
shared, that's the goal of ox.el, but in the end, each back-end decides
how it handles the others.
Regards,
[1] Even then, back-ends are so different that it would ultimately fail,
anyway.
