1. Introducing a whole new syntax that has multiple irregularities (property access) and uses a special character. I sincerely fail to see how this has irregularities. It's straightforward. x.#prop is always a private field access and x.prop is always x["prop"] which is always an object property access. 2. Now can confusingly have the same public and private names on the same class. I know what you're saying, but the reason it is confusing is because it is incorrect. You cannot have have any same public and private names because private names must start with # and public names cannot start with #. Private field names exist only in a class-definition-bound namespace. I know you can't think of a use case. But the committee of TC39 (language maintainers, popular library creators and maintainers) have thought of the use cases and have clearly decided it is useful.
