Can you not work around this with your own "Header set" directives to
override your application's cookies with the proxy's own, or indeed
unset them?

I'm not suggesting this as an alternative to the patch, but rather as
a workaround that'll fix it for you with httpd-2.0.5x as-is now.

Nothing against backporting the patch, but I'd need to review it before
voting +1 (as opposed to +0).
