When using proposal-optional-chaining with babel, the typescript-eslint parser can not resolve the code. It throws the following error: "Parsing error: Expression expected"

err?.errors?.length

This parses correctly with babel-eslint parser.

More generally, is the plan to support all of the babel proposal plugins within typescript-eslint? Now that babel has first class support for typescript, using the 2 in conjunction will be a very common use case.
