Second, Light and Dark aren't official elements in terms of damage, and are always treated as Unaspected magic damage. Aesthetically however, WHM, RDM, and BLM already dip into them - Holy (and Verholy by extension), Glare, Dia, and the Afflatus line for Light, and Foul and Xenoglossy for Dark (utilizing Voidsent cast effects). When Thaumaturge specialized in Umbral and Astral damage in 1.0, Bio was considered the Umbral counterpart to Dia, so you could argue SCH and SMN dip into Dark with it and their Drain spells; this also fits with Broil utilizing the same Dark effects used by Ascians, DRK... or any enemy who casts "Dark".
We also have Wind and Earth available through RDM and SMN. Water's really the only untapped elemental magic - not to say we can't have a caster that dips into other elements as well.
As far as GEO goes, I don't think I've heard anyone propose it use more that Water, Wind, Earth, and maybe Fire.
Oddly picky about your representation.
That's like comparing the RDM we received to the one instance of Alisaie using an aetherial sword in HW.
Bearing in mind "the one Geomancer we saw", if you mean Kyokuho, only had 3 spells. I would highly doubt the devs instilled one NPC with the entirety of their design philosophy for a classic job multiple expansions before hypothetical implementation; all he highlights is that Geomancer is established within the lore, giving it a backdoor for entry as a job should the devs so desire.
