Yes. This is intentional as the client did not signal that it understands
HTTP/1.0 persistent connections. HTTP/1.0 keep-alive was never defined in
any RFC and a HTTP/1.1 client does not need to know about HTTP/1.0
keep-alive, and I judged that it is not safe to signal HTTP/1.0 keep-alive
only because the request was HTTP/1.1.

If you do not agree with this then look for WHEN_SQUID_IS_HTTP1_1 in the
sources, or simply define it when you build your Squid.

As is expected from a HTTP/1.0 style Connection: Keep-Alive indication...
The request protocol version indication is irrelevant until Squid is
HTTP/1.1.
