This was introduced alongside the introduction of the cookies bar in
odoo with [1].
It's not something we wanted but for some internal reason, we were not
allowed to introduce the cookies bar on the website without that warning
when enabling the settings (which also comes with Cancel button as
primary button..).
The compromise was accepted as having a cookies bar was something we
really needed.
It has now been accepted to get rid of it.
While some internal people still think we should educate people about
GDPR and cookies law, I doubt that this settings was the right place to
do it.
Indeed, it was more leading to bad UX as most people just clicked on
"activate anyway" without realizing they still had to save the settings
afterward.
