Sorry, I'm negative to introduce such a function to emacs-w3m
because:

・Though `w3m-filter-delete-regions' might used to have been
  useful when emacs-w3m was appearing, I don't think it's so
  effective nowadays.  Web contents are always liquid.  For
  instance, many of shimbun modules that filter out ads using
  a similar function are now not working.
・I think it would be better for a user to create one's custom
  filter function dedicated to a certain purpose.
・Emacs-w3m is not a collection of function usage examples.
