This kind of already exists. Microsoft 365 is basically office 365 with an included Windows license (and a few other perks) . I don't know if they're pushing it in the consumer space, but they seem to be trying to get businesses to switch.
It's only a matter of time before that becomes normal, I'm so excited for the days when computers come with a trial of ms365 and force you to pay after it expires. Or better yet, buy "extended coverage" to get double the time for triple the price!
Edge has an Internet Explorer mode, which is just running IE with Edge wrapped around it. They're making it harder and harder to use, but they know there are big spenders that will just stop updating if they ever try to take away IE completely. Source: I work in Healthcare IT.
