D&D 5e phb has the example elf shown as Drizzt. A number of elves in the books refer to some specific drow characters as "elf", they're still elves and from a lore perspective, the only real thing that separates them is the curse put on them for their choice to follow Araushnee after her final betrayal of Corellon due to their slow manipulation by Wendonai. The Lady penitent trilogy had a bunch of drow have their curse be lifted due to them not having the mark of wendonai and their abandonment of the drow ways, similarly, at the end of the most recent drizzt book "relentless" there is another event that shows how similar they still are really. Wont say more than that due to spoilers.
Oh, I know they're still elves. When I describe them as 'different' I'm merely talking about their culture, their habitat, society, etc, besides the fact that they're intimate enemies. That's what I meant. The differences between drow and elves (any subrace) are more drastic than all of the elven subraces. If that makes sense? But I have no idea why the devs decided to put them in different race categories, I'm just wild guessing. I agree with you it's likely due to a technical reason.

Feel free to post it in here as well! In fact, we can talk in private if you want so that I can add it to the first post of this thread. We can compile all official information that we have to make a stronger case
P.S: I also intend for this topic to be a general feedback on elves. I haven't added a lot more yet because I'm very slow with my playthrough.
