Fun fact: Comeliness did survive into AD&D 2E as part of the RPGA. However, it was overhauled quite a bit.
You can see this in Polyhedron #89, as an addendum to the adventure "The Ugly Stick." There, Comeliness has a description consisting of three paragraphs and a table, wherein it explicitly says that it's not like how it was in AD&D 1E. Instead, all it does is provide modifiers to reaction adjustments (with the values mirroring those of the reaction adjustments for Charisma).
In the 90s I remember a lot of people using comeliness as a kind of optional rule (don't think it was in the 2E PHB---though that did have a ton of optional rules in it). Personally I was never a big fan of it because I felt CHR elegantly folded in many different characteristics that could make a person appealing (and in real life charisma has a potency that a concept like comeliness doesn't). But I don't think anything was meant by its inclusion in OA other than it being a recently devised stat they felt might meet some kind of demand.
