That's not the point. If it doesn't make sense to new players, it needs to be justified somehow or junked. (IMO, and apparently the O of the 4E design team.)
As someone who's brought in a half-dozen players in the last two years, I will state with absolute conviction that a large number of D&Disms that many veteran players don't even notice cause new players to say "whaaaa?" When bringing folks into my Midwood campaign, it was the D&Disms, not the setting-specific stuff, that regularly stopped the game for a round of "whaaaaa?"
A previous Design & Development article mentioned WotC watching newbies play with just the books from behind a one-way mirror. While they had fun, they got a lot of it backwards and they had a whole lot of "whaaaa?" moments.
"Whaaaa?" moments should always be intentional, and the result of a DM intentionally slinging a curveball, not because of the cruft of a 30 year old game.
