A type used to prevent direct execution of actions on
ConditionalFeature(s), such that
ActionSession only has functions to perform actions using
VerifiedActionBinding and not
perform() using a
This makes it impossible to directly perform an action of a conditional feature without first requesting access to it, as these request instances are only created by the framework and must be used to perform such actions.
The protocol extensions on
ConditionalFeature only supports
request and not
perform, forcing the caller to test if the feature is available first and at least
explicitly ignore the
feature not available path, but hopefully provide a code path for that.
