That is incorrect (IMO).  On a file basis you can turn off most preamble
things via the relevant OPTIONS keyword.

On a project basis you could set the relevant variable.  See

I guess you could make a clever function that sets the org-html-preamble
based on some heuristics and add it to one of hooks that are run before
parsing.  See e.g. org-export-before-parsing-hook.

org-html-preamble-format is a template, it seems, that is used by
org-html-preamble, which can also take a string or a function.  In
practice I always use org-html-preamble in ox-html projects.

Hmm.  Does %d or %C work? See org-html-postamble-format.

Hope it helps,

I almost cut my hair, it happened just the other day
