// Most options are dynamic, which means whenever they are enabled or disabled,
// the effect is immediate. However, some features aren't controlled directly in
// content scripts or injected scripts but instead in the background
// script/service worker.
//
// An example was the "blockdrafts" feature, which when enabled enabled the
// static ruleset blocking *DraftMessages requests.
//
// The "blockdrafts" feature was removed, but this logic has been kept in case
// it is needed in the future.
