That depends on why you're interested in Tor. While my sense is that it was originally designed as an anonymity tool, it seems to have really exploded for use as a censorship circumvention tool.
Most of the latter types of users are probably much less interested in whether the destination website can identify them, and potentially much more interested in Tor traffic going undetected by censors.
