I assume that those HTTP/1.0 requests do not have a 
Connection:keep-alive header.

Good (although some kind of "unexpected post-request data" signal [in an 
access.log record] would be nice for cases where Squid did detect that 
data presence; perhaps that signal already exists).

I believe you are correct.

AFAIK, Squid currently has no code that would treat that post-request 
bytes as a previous GET body. FWIW, it would be fairly easy to hack 
something like that in if (and only if) all those requests have 
fixed-size one-size-for-all-requests "data".
