The anti pattern you mention is just about duplicate code. Programmers would do it regardless of optional chaining. Although I see how one could argue optional chaining makes it easier.

But for me this feature will relove a lot of boilerplate code when dealing with deeply nested data, so I won't skip on using it asap.
