Well, I'm not sure it's QUITE that simple.
Opinion on Ravenloft was ... extremely split. A whole bunch love it, a whole bunch hate it.

I'm going to go out on a limb here and say that a whole lot more loved it than hated. Otherwise, it's pretty unlikely WotC would have gone back to the well a second time for Von Richten's.
See, that's the problem with these conversations. Everyone stakes out positions that are based on their preferences and then tries to pretend that their preferences are the "best way forward". It gets especially frustrating when we start talking about re-releasing material because inevitably it's "Well, it's different, therefore it's bad".
Like I said, we have already got FOUR versions of Dragonlance. You can play a 5e campaign based on Dragonlance in numerous time periods right now. There is nothing stopping you. You have all the material you could ever possibly want already. Thousands of pages of setting material between 1e-present. Never minding the novels, I'm talking about actual setting books and adventures. I know you can do this because I've seen it done and seen it done very, very well.
But, guess what? I don't need a fifth kick at the cat retreading the same stuff yet again. Who gives a rat's petoot about canon? Why can't I have what I want when you've already got what you want? (Note, the "I" and the "you" there are generic and not specific to me or anyone else)
Why do people absolutely insist that the game must never, ever change or reimagine ideas? There's all sorts of really cool ideas in Dragonlance. It's a very popular setting for very good reasons. "Evil wizards must wear black" is NOT the reason Dragonlance is popular. It's like the whole bit about kender possibly being linked to the Faewild.
Me? I thought it was a fantastic idea. DL has always had strong Faewild vibes - the first adventures leading to centaurs and a unicorn, the whole Lorac's Nightmare segment is very Faewild, just as two examples. Giving Kender a faewild origin was actually pretty cool. It explained a lot and opened up all sorts of design space. But, nope. The canon police rush in and bludgeon everyone about the head and shoulders, not because it's a bad idea, but, simply because it's
new idea. It's not what they did back in 1982, so, absolutely not, we cannot do it now.
