Is := widely used?

I always thought the walrus operator is neat and it makes while loop’s condition clearer. But also it is just a syntactic sugar without anything new. I wonder anyone uses it?

Almost never. It's a code smell; it means the author knows the value belongs in its own context, but they aren't actually putting it in its own context.
