Is The trope that wizards can't use armor just an arbitrary limitation?

Sure, but there's hardly any examples of spell-casting fantasy wizards prior to D&D at all. Prospero and the Weird Ladies also don't wear any armor.

Elric of Melniboné. Sheelba of the Seven Eyes and Ningauble of the Eyeless Face.

Which is clearly one of the inspirations for Pathfinder's Magus class. I'm just saying there's obviously a source for the robes and pointy hat wizard that predates D&D.

Yes. Especially with astrological symbols embroidered on the robe it is the get-up of a mediaeval doctor.

Likewise with potions made of weird ingredients, magical incantations in obsolete languages, slips of paper with magical words and diagrams on them worn as amulets, gathering ingredients and making potions at astrologically-defined times and while repeating incantations in obsolete languages, etc.

Medicine has come a long way since Semmelweiss and Lister.

Sure. But there are two different concepts here: The wizard who doesn't go around in armor, and the wizard who is not allowed to wear armor. Or use weapons. Does your mage not pick up that sword because he hasn't been trained to use it, or because it's magically impossible for him to do so, or because his magic will desert him if he messes with weapons? Gandalf, at least, was a pretty impressive swordsman. Or swordsmaia.

Can't speak to original D&D, but AD&D's first edition specified that metallic armors were incompatible with higher magics. They also claimed that mailed gauntlets would interfere with the subtle gestures needed to case spells.

This sort of thing seems to assume a class based RPG - I've only encountered it outside class based games in a context where it appears to be a deliberate attempt to mimic the same effect.
The main reason seems to be either PvP balance or niche protection - explanations given as fluff rarely make any sense.
And of course, there's "that one specific class based RPG" with its origins in wargaming where "magic users" and "fighting men" were simply different kinds of unit with different capabilities, without needing to probe too far into the underlying reality of the thing.
The whole "you can't do it at all because stuff" position is distinctly old school - the modern trend (and the same trend that has always existed in non-class systems) would be towards "you can try, but you'll suck at it" ... which seems far more congruent.

Mythically speaking, wizards tend not to wander about in armour (although sword wielding seems reasonably common), but on the other hand they tend not to shoot fireballs either. Also, most mythic wizards are (or appear to be) very old, which may also impair their fighting ability.

The 'no metal' thing appears in EMPIRE OF THE PETAL THRONE too and I'd give a pretty to know if the Professor stuck that in there before he found DnD or after.

It's mostly a niche-protection rules based thing rather than a mythical thing. GURPS magicians mostly want to avoid carrying heavy loads because that cuts into their fatigue points that they're going to be using to power spells. Which doesn't say 'you can't' but rather 'if you do, you're going to have live with these problems'.

Yes, that seems to be derived from folk tales the the magical fair folk, that is, the Fae, cannot abide iron in any form.

I thought it came from the fae myth that had weakness to iron.
