I understand that, but what Im concerned about is Chrome or Firefox or etc skipping my OS settings and preferences. Like they already do in some cases.
It should teach that Evergreen Browser requires Evergreen OS. And there is long tail.
Windows XP (2001) support:
* Internet Explorer 8 (2009) * Chrome 49 (2016) * Firefox 52 (2017)
IE supported latest versions only, should have been most integrated and now it's dead.
