And it's not like largescale use of Hard-Light Dust has been retconned, considering that we still have Scrolls, and we've seen Hard-Light Dust in use in various other places in the Maya era, if we assume that all projected screens are Hard-Light.

Like, say... TV and computer screens, plus the keyboard for Lionheart's computer.

And it appears that the City of Atlas is completely surrounded by a giant Hard-Light barrier, if you look closely.

Honestly, I believe gravity Dust should be the one that's considered rare, since

1. We haven't really seen it much of anywhere.

2. It seems like it would be more dangerous to mine than the other types, considering that it makes the chunks of land that it's in float. One would assume that, once too much of the gravity Dust is depleted, the sky island will fall, endangering anyone who's still there.
