1. Level scaling? HELLLLL NO. I don't think it really needs much explaining why.
2. Respawning? No again. It just screams "grinding". And then people love it, and you know, they come to the forums and complain the game is just too easy cause they grinded and rofl-stomp everything now. Believe me; It will happen. It's opening a can of worms that adds a negative value whatever way you look at it. So why should they waste developer time adding it.
That doesn't mean I disagree with certain events opening up new content (and potentially a battle) in older areas. Like in Area 3 you run into a NPC who tells you evil wizard X took over the lair of the forest after you cleaned it and is using it for pure evil. And if you return, new opponents are there, not just a rehash of the ones you killed before - as akin to the new quest/encounter that lured you back there.
Several other ideas could be the treasure hunts of before (expanded, and sometimes luring enemies to itself), fighting a "lair" (kinda needs objective XP (hell yeah) though or no XP for the lair summons) or as stated bounty hunting.
There's so much one can think of, but just respawning the same enemies will only harm the game and is, at best, a completely lazy cop-out. A big no.

Not to sound mean, but you type lots and make little sense. Going HELL NO to level scaling then going to respawning and saying will stomp it.. well yeah, that is where level scaling comes into play. To keep it a challenge. But I can see Divinity Original Sin 2 will be just another rush through to the end credits game.
