For me D&D canon is sort of interesting on occasion but as pointed out there are so many versions of canon that I pick and choose which bits of canon I want in any new campaign I run.
This is largely my approach. Whatever is in the books is there for inspiration AFAIC. If I like the idea, fantastic. Yoink and off it goes into my campaign. If I don't like it, change it and go with whatever I do like. To me, D&D lore is just the starting point. It's what you jump off from, not to. Having three different versions of Lolth is a good thing. Having three different versions of Demogorgon (3e) is a good thing.
Y'know, it's funny. I've been told time and time again that something like Planescape and the Great Wheel is just one interpretation of the cosmology of D&D. That multiple interpretations are not only possible, but, expected. But, here's the trick. Any time someone comes along with something that isn't toeing the line in Planescape and the Great Wheel, it's automatically bad.
It's just so baffling to me.
Heck, look at a kobold. These are all kobolds:

and there are certainly more where that came from. All of those are canonically kobolds. So, what does a kobold look like?
As I've repeatedly said here, canon is only important when it intersects with personal taste. Adding a second teaspoon of salt doesn't ruin the dish. It ruins the dish for you. For others it's perfectly fine. IOW, there's nothing inherently wrong with adding more salt or changing the flavor of the dish. It's only important when someone doesn't like the new flavor. But arguing that adding more salt or changing flavor is inherently bad or that a specific flavor somehow holds a priveleged position because it's what you happen to like is just arguing in bad faith.
All you can say is that you don't happen to like it. Fair enough. But, "I don't like it" doesn't make anything bad. It just makes it not to your taste. And then turning around and forcing everyone else around you to eat what you like is a douchey thing to do.
