WKA was decided in 1898 after Elg, so WKA is the law of the land unless overturned, as confirmed by the title of the article you quoted:

“Was U.S. vs. Wong Kim Ark Wrongly Decided?”

WKA granted 14A citizenship, but not NBC status, to at least some children of aliens born on US soil. SCOTUS has yet to clarify how extensive that grant of citizenship is beyond the relatively narrow situation of Wong and Wong's parents.
