The Squid Project does not collect customer statistics but there is
plenty of evidence that Squid HTTP/0 code is still in use. Naturally,
most of that evidence comes as bugs related to misinterpreting malformed
HTTP/1 traffic as HTTP/0 but, IIRC, intercepting customers still see
genuine HTTP/0 _requests_ from various scripts and devices. Some of
those requests may expect an HTTP/0 response...
