Can anyone see any reason why a proxy request should have the URL changed?
For a forward proxy, that's right. For a reverse proxy, no. Of course ProxyPass and family modify URLs.
I am not sure I understand why a forward or a reverse proxy should modify the URL that is sends to the downstream server. I see no difference between the two - I think the unmodified URL should be passed as is.
As for mod_proxy's internal handling of the URL, there is a need to decode the URL, as requests for /%41%42%43 and /ABC must both match the ProxyPass defined for /ABC which they only will do if decoded first.
