Such care is seldom seen! But I think that we don't need to worry so 
much. Currently no proxy that doesn't preserve the HOST header will 
work. The simple fix will work at least with Apache/mod_proxy and squid.

I trust that we can test the patches with the setup mentioned above, but 
certainly a hook gives an extra level of flexibility.

PS: BTW, you don't need a hook for that. I have written an extension 
that modifies the environment itself. If you change localconf.php so 
that it is loaded very early TYPO3 won't ever see the original 
environment. This trick worked well in my 2 current proxy installations.
