The issue that lead to some of us fitting manual tensioners was because there were some (very few) reports of the manual tensioners getting stuck and allowing the chain to jump the cog leading to catastrophic engine damage. I don't think there was ever any talk of the cam chain stretching so much that the automatic tensioner was unable to cope, but happy to be otherwise educated. 99.9% of owners will never have an issue, those of us glass half empty types concerned that we will inevitably be within the unlucky 0.1% fitted a manual tensioner just to feel that bit safer, but no it definately isn't a must.
