== Description
We would like to explore the feasibility of providing opt-out and A/B testing capabilities to logged-out users throughout the course of the desktop improvements project
== User stories
As a product team, we would like to A/B test desktop improvements changes (such as changing the location of the language switcher) on all users (logged-in and logged-out), so that we can determine whether the change has any positive or negative impacts
As a product team, we would like to allow all users (logged-in and logged-out) to be able to opt-out of the new experience, so that we can measure the retention rate for the new treatment
== Acceptance criteria
Research the following questions (and consult with relevant parties such as the Traffic team):
- Is it possible and what is the relative difficulty of providing all logged-out users with an opt-out option for the proposed improvements
-- Does this change based on how many wikis we are testing on?
- Is it possible and what is the relative difficulty of performing per-user or per-session A/B test on logged-out users?
-- Does this change based on how many wikis we are testing on?
