CASA prints various "educational material", then "some" FOIs "informally" makes it abundantly clear that "V1 cuts" (in an aeroplane where a V1 performance simply does not exist) will continue to be conducted, as will landings with one engine feathered, as opposed to zero thrust. The "educational material" will be ignored.
This subject goes back well over sixty years. A DH Dove crashed at Camden during a supposed "simulated" engine failure at lift off. The pilot was a DCA Examiner who was being supervised by a Bankstown factory representative who was a demonstration pilot. The Examiner proceeded to fail one engine on himself just after lift off and feathered the prop. The demo pilot expressed his grave reservations about this intention especially as Camden Runway 06 had rising ground in the take off splay but the Examiner went ahead and feathered the prop anyway. Control was immediately lost and the Dove went in killing the Examiner and severely injured the demo pilot. See:

For many years in the late 1940 and 1950's the RAAF practiced engine failures after take off in the Avro Lincoln four engine bomber and other twins as well as practice feathered landings. Then circa 1953 a Lincoln was carrying out a practice asymmetric landing at Townsville with No 1 engine prop feathered when it began to drift towards the side of the runway due crosswind.
The instructor attempted to go-around on three engines but got into Vmca difficulties and the Lincoln crashed and burnt. Luckily, the crew of three escaped before the aircraft was destroyed by fire. Five years later at Townsville a similar accident happened to a Lincoln during a practice feathered landing. This time a new pilot was being checked out by an instructor. Again No 1 prop was feathered. The aircraft bounced heavily on touch down and the instructor took control to go-around on three engines.
Same old problem when the Lincoln ran into a Vmca situation and control was lost, crashing near the then civil terminal building. The crew were lucky to escape before the aircraft blew up.
Soon after, the RAAF banned practice feathered landings and after that zero thrust throttle closures were mandated for practice engine failures after take off and for practice asymmetric landings. The DCA did not follow suit and continued to permit simulated engine failures in civilian registered light piston twins by use of mixture lever cuts after lift off. In fact it is not unknown for some instructors to cut the mixture on piston twin during the take off roll for practice abort. Instant correct corrective action is required if that happens since no delay in closing the throttle of the operating engine is vital to prevent loss of control on the runway.
Finally, it is worth studying the ATSB report on the 2003 accident at Camden NSW to a Duchess where the instructor cut the mixture at lift off during a touch and go.
That aircraft crashed and caught fire and the instructor lost his life. Both pilots were highly experienced former airline pilots. See:
