The same reason I'd like to see a lot more things become dangerous for a high-level character: to make them mortal again. If I wanted to play supers I'd find a Marvel game.Although it may be getting off-topic, I wonder, why would you want falling to become dangerous for a high-level character?
Beowulf is in my view considerably beyond simply being 'high level' and in game terms would be deep into epic, if not on his way to divinity. I prefer a flatter power curve, where the dozen spear-carriers on a good day could pose a threat to the high-level guy that'd be worthy of his attention.If you're playing a high-level character, like Beowulf, the you can laugh at a dozen warriors with spears pointed at you, because you know with relative certainty that they can't actually do you any real harm (at least, not anytime soon). Why should such a powerful being be afraid of a mundane threat, like falling? At that point, if a fall could easily kill you, then it would drag you down out of the power fantasy.
Keep in mind also that death at high levels isn't usually much of a headache as by then most parties have raise or even resurrection capabilities in the field. (though I also prefer that death have some lasting aftereffects on revival - 1e's loss of a Con point works well here)
