This change would appear more acceptable if it was combined with removing the Fedora user
agent patch for Firefox
(
https://src.fedoraproject.org/rpms/firefox/blob/master/f/firefox-fedora-u...), which
is simultaneously a worse privacy risk and a worse way to count users than randomized
UUIDs.
Also, since there is no need for a highly precise count, the UIDs do not need to be so
unique.
