Note
It’s not required for service owners to support keepalive. Client authors must
coordinate with service owners for whether a particular client-side setting is
acceptable. Service owners decide what they are willing to support, including
whether they are willing to receive keepalives at all (If the service does not
support keepalive, the first few keepalive pings will be ignored, and the
server will eventually send a GOAWAY message with debug data equal to the ASCII
code for too_many_pings).
