It isn’t at all a logical end point for what wotc is doing, it’s very much your solution.It's a question of whether or not you try to anticipate every combination the players might want. Sure, you can create a race/lineage for both elf and wood-elf. But what if a player wants a wood halfling? Do you just disallow that, or do you also have a a lineage for generic "forest folk". If the latter, there are now two very different ways of creating forest-folk.
I mean, one could solve it by adding a fourth option to chargen, so you choose elf as your race and forest folk as your lineage, but we both agree that's not a good solution.
Alternately, background could be co-opted, but that changes the meaning of background.
I agree my solution* wouldn't give people what they're used to getting, but it's a good solution.
*It's not really "my" solution; it's the logical end-point of what we see in the lineage UA. If WotC doesn't do this, they're essentially going to have a weird hybrid system that only makes sense to people who have been playing for a long time.
And Background can grow to encompass upbringing just fine, while it would be incredibly weird, jarring, counter-intuitive, and limiting, to have to choose between elf and Underdark dweller to make a Drow.
Your solution makes it so, to make a Drow, I can either pick Elf, and use backgrounds as they are now and class and maybe feats or whatever to hack together something that feels like a Drow, or choose Underdark (or evil matriarchy or whatever) and then use background and class and whatever else to kludge together something that feels like an elf.
That’s a bad system.
EDIT: okay, your idea has merit, just not in a D&D PHB. I’d enjoy a fantasy game where stuff like forest folk and seafarers and insular clan-holds and whatever else are the lineages available, with no stuff like “elf” available alongside. It’s just choosing between having a race or having a culture/regional adaptation set, effectively, that I don’t like.
