The change that had this effect dates from May 2018 and has been "in
production" since the 5.6 release in September 2018, so I think it's
reasonable to say that it hasn't had any significant impact on usage
-- MacOS Catalina has zsh 5.7, Ubuntu 20.04 has 5.8 -- but it's
probably worth mentioning somewhere.
