There are some things that just don't look nice under Best Practices.
But I'll take Best Practices over Pig Lipstick any day of the week.
2.1 Privacy Considerations

This section is non-normative.

Using unique identifiers (e.g., a UUID) as an instance identifier can be exploited by an adversary as a digital finger print. This can allow a developer to, for example, restore cookies even if the user has cleared cookies from a user agent. As such, if the user agent relies on unique identifiers as the host component, then it should provide end-users with a means of regenerating the authority component. For instance, A user agent can the regenerate the instance identifier when the user clears the user agent's private data.

 However, never seems to catch
