Hello,

You may want to read the discussions about this feature on the ML.

I think "only" is not accurate. To make it clear, what would become the
following documents:

--8<---------------cut here---------------start------------->8---
* H

Text

** H2 :ignore:

Text 2

*** H3
--8<---------------cut here---------------end--------------->8---

and

--8<---------------cut here---------------start------------->8---
Text 0

* H :ignore:

Text

** H2

Text 2
--8<---------------cut here---------------end--------------->8---

but also

--8<---------------cut here---------------start------------->8---
- item
* H :ignore:
- new list?
--8<---------------cut here---------------end--------------->8---

and the following convoluted one

--8<---------------cut here---------------start------------->8---
#+begin_example

Something

* H :ignore:

Somethin else
#+end_example
--8<---------------cut here---------------end--------------->8---

I'm not sure to understand this.

The manual gives one example of one such hook, see (info "(org) Advanced
configuration"). There, the filter /only/ removes headlines.
