I think EasyJet has (or at least had) it written in their OM's... I tried it a few times and found it awkward - I discovered I normally grab the lever from the side (never paid attention before)
In my opinion this kind of error, while possible, is statistically insignificant (I think I've seen in once over 10+ years of flying) and potential consequences not very severe (an overspeed inspection at worst, which happens anyway from time to time due to multitude of reasons).
Adding yet another minutae to the SOP's is an overkill to me - we have to deal with enough crap on daily basis already...
