Which we know from the IE dominated era does not matter, people just switch to the browser they have to use. The overwhelming majority of users do not know what a user agent string is, let alone how to change it they just see an increasing number of sites saying "you need to use IE/chrome". Moreover, again from the IE era - and we already see this with chrome - people make their sites work in IE/Chrome and then label any browser doing something different as broken so as people are increasingly forced to use chrome the degree to which spoofing does not work steadily increases.
