Description

Some cases may require a server certificate to be used to authenticate a server (to client) and authenticate as a client (to another server). Currently, server certificates only include the serverAuth EKU, but both may be present.

Additionally, the ISRG-CPS-v2.6 standard followed by Let's Encrypt contains both for end entity certificates.

Looking at some other standards like RFC 5280 (EKU), RFC 5216/RFC 5281 (EAP-[T]TLS) they all mention things in a permissive way, meaning that the presence of specific values enables uses. I don't see anything that would exclude or fail based on the presence of an EKU.
