I think that this is wrong, because of this sentence in RFC 7540:

A server MUST ignore an "h2" token in an Upgrade header field. Presence of
a token with "h2" implies HTTP/2 over TLS, which is instead negotiated as
described in Section 3.3.

Isn't that referring to inbound Upgrade headers?

Yes, you are right. But with the response header "Upgrade: h2", Apache is telling the client "you may send such a header" when in fact this is not allowed.
