Conceivably, yes. Though I would maintain that *by default* people with 
reverse-proxies would want/expect all their headers retained intact.

Not sure what you mean there - ProxyErrorOverride is a directive for 
mod_proxy...

In any case, it does not allow one to rewrite the redirect URL. The 
2.2.4 behaviour is that the Location header gets retained as-is, but all 
other headers are stripped out - and I can't see why anyone would want that.

> Looks to me like a valid usage case for ProxyErrorOverride 3xx.

I don't see how it would achieve what you stated above. If you do want 
to rewrite headers (Location or any others), the code that deals with 
altering the response for what are considered error pages is surely not 
the place to do it.
