EphemeralValuePaths returns the paths within the given value that are marked as ephemeral, if any.

NonNullWriteOnlyPaths returns a list of paths to attributes that are write-only and non-null in the given value.

RemoveEphemeralValues takes a value that possibly contains ephemeral values and returns an equal value without ephemeral values.

ValidateWriteOnlyAttributes identifies all instances of write-only paths that contain non-null values and returns a diagnostic for each instance.
