ESNI is still in draft, and not going to be supported by OpenSSL until after its standardized, and can't be supported by Node.js until OpenSSL supports it.

• https://tools.ietf.org/html/draft-ietf-tls-esni-05
• Support Encrypted Client Hello (formerly known as ESNI) openssl/openssl#7482 (comment)

Re-labeled since this is blocked by missing features upstream.

[bnoordhuis]

ESNI never left draft status. It's been superseded by ECH, which is in draft: https://datatracker.ietf.org/doc/draft-ietf-tls-esni/

openssl/openssl#7482 is still upstream's tracking issue. My hunch is it won't be available before 2023.
