This will use browserSetting  to manage which extension has control over the pref. This does not really belong in privacy so will go into the browserSettings API.  https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/privacy/BrowserSetting
This is no longer a supported configuration. Allowing add-ons to change this on a per-site basis is one thing, but changing it for the entire browser is a different matter.
Updating the title to describe the use case, rather than the implementation. Kris, if this is no longer supported is there something else we can do to support this requirement, or are you saying we just need to WONTFIX this?
Caitlin, can you please add this to the next design-decision-needed triage? It sounds like we need to make a group decision about this.
