Realistically, no one will care all that much about more than 3-4 stats.
As soon as you want 4 stats, you're getting a discount on those you actually want, and get those you don't want as bad thrown in for free. Even with 3 needed ones, you're getting the others for a very cheap price.
It surely isn't for everyone, but it's not that rare, either. Let's look at the base classes:
Fighter: Str and Con are a must for your average fighter, with Dex being important, too. You can kinda ignore Int and Cha, but Wis is helpful to get at least a fighting chance, as it were, to make will saves. Might benefit from this.
Barbarian: Similar to fighters, but Dex is more important due to armour limitations. Might get interesting, if only to have the gloves free for gloves of storing.
Paladin: Str, Con and Cha are a must. Int is not that important, and neither is Dex, but Wis is useful, too. Will definetly find those useful to get gloves of storing (to better cast and fight), cloaks of resistance, and amulets of natural armour and still getting their ability scores buffed
Ranger: Needs Str, Dex, Con, and some Wis. Will find it useful, to get bracers of archery, gloves of storing periapts of wisdom, and so on
Monk: With Str, Dex, Con and Wis needed a lot, it's almost a must - Int and Cha won't hurt (and just think of the Monk/Paladin combos).
Cleric: Needs Con and Wis (Str is taken Care of by Divine Power). Cha is also often quite helfpul because of Divine Feats (and turning). Won't spit at the rest.
Druid: Well, since they spend a lot of time in other shapes, they might not be too keen on many magic items, either, unless they somehow make them work in the wild shape. In that case, they'll need Str, Dex, Con, Wis (and the other two won't hurt, either)
Bard: Your average bard needs Dex, Int, Cha (and Str, Con and Wis don't exactly hurt), and would like to use a cloak of resistance, gloves of storing, bracers of archery (depending on style)
Rogue: Similar to the Bard, a well-rounded rogue will need most stats - Str for fighting (unless he uses weapon finesse) and skills (though there are feats for that, too), Dex (no doubt), Con (like everyone), Int (for several key skills), Wis (for perception skills and will saves), Cha (for social skiils, UMD) - and be more than happy to be able to use numerous items, such like boots of speed, gloves of storing, bracers of archery, cloaks of resistance, amulets of nat. armour, and so on.
Wiz/Sor: Actually the least likely to take those, since they have one big primary ability (Int or Cha) and two secondary ones (Dex, Con), but still not that bad.
