This is like a #feature - #dev topic, not sure which one it should be in. Is there a way to modify site settings in a plugin? I’m 99% sure there isn’t, but I’d just like to confirm that. If there isn’t, can I put forward a suggestion to not make it immutable? Or perhaps, having some API or a way to ‘unlock’ the immutable property of SiteSettings, perhaps? A possible use case I’m looking at is to the include a list of protected categories to a setting such that it’s easier for the admin to include/exclude them. Thanks.

Although that is perfectly possible from a technical point of view, I think the approach would be over complicated, especially since “at the start” is hard to define/detect, and you want to avoid that the plugin keeps adding B back after the site admin removed it. Also, when a new private category is added, the plugin would need to add it to the setting, but it would need to be able to see the difference between a new category (add) and a category that was previously removed by the admin (don’t re-add). I would opt for a include_private_categories setting which starts out empty, and the plugin would simply process all public categories, AND the categories in include_private_categories. That will give you a lot less headaches. Also, from a functional point of view, that makes it more easy to spot which private categories are being shared (in your approach one would have to have a list of categories in their mind and then determine which ones are missing by comparing them to the ones in the setting).
