Even then there isn't that great of an incentive for Drow IMO. Minthara's a heretic and so far the singlemost Lolthsworn-drow thing you can do- is locked behind killing her.
Apparently if you killed her previously you can convince Nere to abandon the absolute and go fetch a particularly infamous and fanatical group of Lolth's worshippers to come down on the cult like a hammer.
So even the nastiest of Lolthsworn drow, like a cleric of Lolth has a pretty good incentive to not touch the cult of the Absolute.
