Dear WT,
The perennial discussion about ways to provide logged-out users with
persistent customization of their reading experience in the browser has
cropped up again in the context of the pending deployment of Vector 2022.
Can a cookie-based width toggle
<https://en.wikipedia.org/wiki/Wikipedia:Requests_for_comment/Deployment_of_Vector_(2022)#Alt_proposal:_gradual_changeover_+_width_toggle>
be offered without splitting the cache or otherwise making the toggler
regret their tog?
The answers currently range from "*shouldn't be very complicated or hacky,
just toggling a class*..." and "*can be delivered to logged-out users on
top of the cached parser output*.." to "*impossible*".
Could someone clarify the challenges and costs of trying to toggle css
classes in this way?
Warmly, SJ
