+.. note::
+
+   **Historical context**: Web Support originated from the `Pocoo`_ community,
+   the original creators of Sphinx, Jinja, Flask, Pygments, and more. Web
+   Support was part of a plan to create a forum application that tied together
+   Jinja, Flask, Sphinx, etc. The core goal behind Web Support was to enable a
+   user editing and suggestion layer on top of documentation. While the concept
+   has merit, the feature has seen limited adoption and development over the
+   years. As of 2025, there are few real-world examples of its use. See
+   `sphinx-websupport-app`_ for one such example.
