Less so, I think, because a) there are so many combinations of such stuff; this means you won't get four characters in the party who all have roughly the same magic items; b) such items are certainly useful, but not as universally useful as the Doodah of primary ability +6 and, c) with the characters gaining more abilities on their own, there is less of a problem of a marked difference in adventuring efficiency between a character who's used his hard-won gold to buy land or houses, throw elaborate parties etc., and another who's blown everything on equipment.
