// Unlike the private version (which lives in
// blink/renderer/core/permissions_policy/), these maps will include all
// features, regardless of whether or not they depend on a blink runtime enabled
// feature that is enabled/disabled. Features which are shipping as part of an
// origin trial add their feature names to this map unconditionally, as the
// trial token could be added after the HTTP header needs to be parsed. This
// also means that top-level documents which simply want to embed another page
// which uses an origin trial feature, without using the feature themselves, can
// use permissions policy to allow use of the feature in subframes (The framed
// document will still require a valid origin trial token to use the feature in
// this scenario).
