... but the patch claims to have no affect on cases where Squid responds
with an error page. That choice made it possible for that implementation
to be configuration-free.

If Squid starts forwarding *all* connection resets to clients, then some
admins will rightfully complain that their users deserve a nice
proxy-generated error page with a support ticket submission interface
(instead of a silent connection reset with a confusing browser error page).

In summary, no single behavior will satisfy everybody. We need a new
configuration option flexible enough to cover known use cases, including
Alessio's. For example, on_server_error with "retry", "respond", and
"terminate" actions (ideally with an ACL to detect cases where there are
no unused peer addresses left to try and an ACL to count the number of
retries for the current peer address).
