What format has "heading pre-output generation"? Is a string or is it
parsed data? The first part of your paragraph sounds like you want to
rewrite an Org parser.

How do you pass it to ox function responsible for using the title? I.e.,
who/what is responsible for making the change to the title? Is it the
user?

You may need to clarify your specifications.

In `org-html--build-meta-info' from "ox-html.el", replace the following

  (org-html-plain-text
   (org-element-interpret-data (plist-get info :title)) info)

with

  (org-export-data-with-backend (plist-get info :title)
                                (org-export-create-backend
                                 :transcoders
                                 '((bold . (lambda (_ c _) c))
                                   (italic . (lambda (_ c _) c))))
                                info)

Now re-evaluate the function `org-html--build-meta-info' and try
exporting a document to HTML with a title containing bold and italic
syntax, even nested, e.g.

  #+title: /Some *bold* text/

Adding the function `org-export-strip-syntax below to "ox.el"

  (defun org-export-strip-syntax (data info)
    (org-export-data-with-backend data
                                  (org-export-create-backend
                                   :transcoders
                                   '((bold . (lambda (_ c _) c))
                                     (italic . (lambda (_ c _) c))))
                                  info))

you can now call it from any export back-end whenever its needs to
remove syntax from a piece of code.

You can also drop the info argument and add it to "org-element.el". But
it depends on what you want to obtain. Also, some syntax is not obvious
to strip, as I suggested in my previous message.
