Modern good games are not expected to "render in “borderless windowed” mode, so you can alt-tab out to multitask"

Really bad games with slow multiplayer match making lobby and tiresome repetitive gameplay and bad UX where you need to look most of the actual game information on a fan wiki, or triple A games where you have to login and enter credit card information on a "launcher"... those are the ones you expect to "render in “borderless windowed” mode, so you can alt-tab out to multitask". Good riddance.
