I'd prefer to ask Emacs upstream first.

We are discussing adding a new feature to Org imenu - an option to
flatten the menu, so that all the nested index entries are displayed at
top level.

This feature is also present in doc-view via `doc-view-imenu-flatten',
and in python.el via `python-imenu-create-flat-index'

I am wondering if it makes more sense to add this "flatten" option
globally into imenu instead.
