brit bus driver, that's what a senior air trafficker told me and I assumed that it was therefore correct....
I think the 'autocoupled approach' ban on RW08 came in after the TriStar incident. Caused by the reasons you give. But I've certainly flown auto-ILS approaches in the VC10/VC10K on RW08 for training in VMC and the aircraft was able to follow the undulating glideslope reasonably well... But, having been taught by 'JR' about such things, I always checked proper autothrottle operation on the ground first - even though a certain lazy individual had demanded that the check was taken out of the FRCs as he considered that it "Wasn't necessary". Bolleaux - of course it was!
