Of course, some controllers do need to redirect and cancel streams. Fingerprinting resistance In some protocols, like HTTP, subresource loading behavior can be a fingerprinting hazard. Streams opened by Tor Browser can be disambiguated between 1st-party (safe to tamper with) and 3rd-party (fingerprint risk if tampered with) by whether the SOCKS5 username contains the eTLD+1 of the destination hostname.
