While I can see the benefits of trying to narrow the argument (gameplay concerns do not by necessity remove the paladin, so I don't think it's fair to say you're trying to eliminate disagreement), I'm still not entirely sure how to respond to it in that context... Gameplay doesn't exist in a vacuum, and there is no singular ideal -- you have to evaluate gameplay in terms of the goals of a specific system. Hopefully that's not too far from your ideal context, because that's where I'm going 
You see, D&D is a gateway RPG. Although Wizards is concerned with appealing to the old school gamers as well (hence the rather well-engineered d20 system), they have to acknowledge the fact that it's the sort of game first-time role-players will have the opportunity and interest in joining. It has to be playable right out of the box.
Now, first-time gamers don't look for solid mechanics (although they benefit if they're easy to understand) or versatile options -- they just want to play a cool character... (Ah, how I love first-time gamers
) Which is where classic archetypes come in. They provide a nifty little package which can be customized, sure, but still stands on its own as Fun to Play.
The new gamer who wants to play a Joan of Arc type? Out of luck without the paladin -- oh sure, maybe multi-classing won't go over their heads, but a Fighter/Cleric just isn't quite the same, and a prestige class? What's that?
Now, that's how the logic makes the paladin fit for 3.0... 3.5, well, it's a little different. While it still has that to worry about, it's also sort of an upgrade for current players, some more depth, some more versitility -- "options, not restrictions." In that light, I could see making a less rigid paladin -- the holy warrior that's been described, but let's call it a paladin just to piss off the diehards
Something that's still playable out of the box, but with plenty of room for twists (Number one on that list: Alignment restrictions should get nixed).
D&D, however, is not and should not be simply "d20 fantasy" in the same vein as d20 Modern... for d2M the stripped down, flavorless class system works: Its market is more the long-term gamer (who the hell, having never played an RPG before, sees "d20 modern" on a shelf and says "oh! that looks fun!") -- people who are quite used to using rules to create their own flavor. But that is not the audience for D&D, and it never has been. Which is why gameplay concerns are what they are..
