The issue is that if HTTP is an extra 50ms than TCP for example, if you increase TCP by 50ms now HTTP is 100ms more. Basically it is always more no matter how much you increase it.

If the proxy can "see" the requests, then this isnt an issue because the headers can be trivially be modified.
The problem is that the proxies which are targets of identification - think proxies for large scale web scraping which use CONNECT tunnels - dont get to "see" the request.
Not if you receive the HTTP request from the client first, before any interaction with the end-host.
