"Lolth-sworn" Drow and "Seldarine" Drow are really dumb sounding names. And because of the deities involved in the name, it makes it seem like they can only exclusively worship one particular deity or one particular set of deities.
Illythiiri Drow and Miyeritari Drow would be the only two drow cultural groups that would have some basis as a "subrace". Ilythiir was a decadent, warmongering and cruel dark elf empire in South Faerun that threatened to conquer the rest of the Realms some millennia ago from the other elves, while Miyeritar was relatively a peaceful dark elf kingdom in the North that was brutally subjugated and later destroyed by the sun elf empire of Aryvaandar. Though Miyeritar had little connection to Ilythiir, many were conveniently blamed for colluding with them in the Crown Wars, and their people (those few that survived the Dark Disaster that turned their country into a barren wasteland) were subject to the same curse that was meant for the Ilythiiri dark elves and which consequently drove both groups to the Underdark, and later they would emerge as the drow race. Many Eilistraeean worshippers are descendants of Miyeritar, whereas most Drow in the Underdark (i.e. the evil-oriented) are descendents of Ilythiir. The ancient Ilythiiri dabbled in dark arts and their ruling class consorted with demons and most notably with the demon lord Wendonai, and many carry his taint in their blood which might be an explanation to their "amoral" tendencies, while Miyeritar Drow purportedly have less demonic influence and are more predisposed to worship Eilistraee like their ancestors did.
Still I would rather prefer to see High Elves split into Sun Elf and Moon Elf, like in NWN2 and IWD2, than see the drow race split.
