The most Limited Content: Low-Level Dungeons

It's more the opposite: I would be confused why a RDM can not raise or heal or do even a real melee rotation or when a White Mage with glowing weapons restricts him- or herself to the very basic first aid skills and you die from "something" you have skills for in your bar but greyed out.

Why would a new player be confused? The new player isn't going to know what's part of the job toolkit.

The irony is that always it's the higher level players who are ignorant about other jobs that start screaming for the RDM to rez a healer in low level dungeons.

If you are dying from something in a low level dungeon, that's a learn to play issue. Dungeons are designed for players to survive on what they have in their toolkits at the dungeon's level, not what's in the toolkit 30 levels later. Making those later abilities available would break the dungeon experience because you'd be nigh invincible.

Eh, just give some aoe to most jobs at level 20 or so. It's kinda ridiculous on NIN, when earliest you have some sort of aoe is Quarn, and that's on 20 seconds timer.
