Shouldn't this proposal be at stage 2?

It is still at stage 1; it requires TC39 consensus to be stage 2.

The precise syntax must be resolved prior to stage 2, particularly because this proposal interacts with nullish coalescing and possibly other future proposals.

The champion has indicated that they will seek stage 2 in the March meeting.

feat: Add optional chaining to the babel preset
b7b005e 
[Optional chaining](https://github.com/tc39/proposal-optional-chaining)
allows to chain potentially null components.

Instead of doing
```
if (window && window.location && window.location.protocol) {
  ssl = window.location.protocol
}
```
we could do
```
ssl = window?.location?.protocol
```

The spec is stage 1 only but [they seem to have reach consensus](tc39/proposal-optional-chaining#75 (comment))
and [the formal stage 2 decision should be in March](tc39/proposal-optional-chaining#76 (comment))

There should not be any compatibility break
