I quite agree with that. Unfortunately you have mis or selectively quoted, because 2.2.8 concerns upset recoveries and not specifically stall recoveries, which were covered in previous sections and 2.2.8. commences with 'High speed high altitude flight'
If you read on a little, paras 3.3 1a and 3.3 3 b specifically discuss the way rudder should be used in LOC recoveries. Rudder is also taught as a means of inducing roll at extreme pitch angles durng upset training and from the same document from which you quote
If control provided by the ailerons and spoilers is ineffective, rudder input may be required to induce a rolling manoeuvre for recovery. A small amount of rudder input is sufficient. Excessive rudder applied too quickly, or held too long, can result in loss of lateral and directional control.
The simple message, however, is if you do not know what to do with the rudder AND how to do it, it is best to leave it alone. Applying incorrect rudder is a sure path to a further disaster than the one you are in.
