I agree that the main scenarios people are excited for are probably the exact opposite of the ones we should be looking to solve with this. Indeed my last comment right before posting this was about how callbacks are better than we remember (and if we were on ts when using them, probably wouldn't have minded at all). Deeply nested object props are often bad, except for when it's a big dynamically-defined object (eg a directory tree that you would traverse with lodash get). It's also great when you're not deeply nested, you're simply checking for the inclusion of something in a collection that is itself optional. Eg a Map#has on an optional map.
