Got it, thanks.

My concern is this: it would be nice to provide a simple way to get
rid of _anything_ (user defined) in headlines and TOC titles.

Actually, the org-export-with-* family contains two categories of
variables: those who are relevant for anything in the buffer, those
who are relevant for the headlines only.  Like these ones:

org-export-with-priority
org-export-with-statistics-cookies
org-export-with-todo-keywords
org-export-with-tags
org-export-with-section-numbers

I set aside the last one, which does not impact the text of the
headline itself, but the way it looks in the target format.

My suggestion is to get rid of these four headlines-only
org-export-with-* variable, and to replace them with

org-export-headline-format
org-export-headline-in-toc-format

with formatters to tell whether to include the TODO keyword, the tags,
the priority cookie, the statistics cookie, the headline text, etc.

And two generic options

org-export-headline-trim-regexp
org-export-headline-in-toc-trim-regexp

which the user can set to whatever he wants.

I think a formatting string for the headline is good as it is quite
intuitive for a vast majority of users.  And the -trim-regexp options
would be flexible enough to remove anything from the headlines.

Please *don't* implement this :)  I just need your gut feeling 
about org-export-headline-format as a formatting string, and if you
think it might be a good idea, I'm willing to help implementing it
(as I know it will change quite a lot of things in the machinery.)

Thanks,
