and as an added note, an old acquaintance of mine, who is a doctor, and serious biker, always considers bar ends to be dangerous pokey things in your chest or whatever in the event of an off.
He mountain bikes and whatnot, so knows the biking side, but maybe his view is shaped from seeing ER visits of folks who have had impalings etc in car accidents and colours his view of the danger with bar ends.

I've ridden with bar ends on mtb bars for ages, and really like their position, like mentioned in that article.
So crazy as it seems, I might try this goofy setup one day, just for giggles.
