My guess is it'll never have an official Linux release. Besides, proton is so good at this point that it will usually outshine a cheap Linux port. In fact, due to the lack of backwards compatibility in Linux land, the Windows edition of a game will typically keep working longer on Linux than the native port. It's a really strange situation.

What does "Finished" mean to you?

BG3 was "finished" on release. If it never saw a single update after that, I'd have been happy with it anyway. What they're doing is providing excellent ongoing support to an already solid product.

The game is finished.

They're still releasing patches, so this is an exaggeration. It's very playable, though.

I don't understand which part of releasing patches would not imply it's finished? The campaign is whole, the story is done, the classes are there. There's nothing missing.

For what it's worth I was experiencing crashes on Patch 5. No crashes on the recently released Patch 6 and the performance is better as well. As a Steam Deck gamer, I appreciated Larian adding FSR support as well. It's not an exaggeration to say that people who start playing now are getting a substantially smoother experience than those who played on Day 1.

The game launched yesterday on Xbox and those folks are going to have a blast. :)

They haven't stopped working on it, so it's not finished. That's what the word "finished" means.

It's a very odd definition in the world of software though, even games. Hope they're not holding their breath for World of Warcraft or Factorio to be finished. God forbid they need an operating system. I guess OS/2 would make the cut :-)
