I was going to say, having read the chart: a little surprising that Windows 11 isn't on here somewhere, wonder if it just advertises as 10.0 still. And apparently it does.
I wonder if we can get to a default User-Agent string for a browser where just none of the information it contains is accurate. Lying to say you're "Mozilla 5.0" is ubiquitous, now we've got lying about the version of the OS you're on and lying about the architecture... the only stumbling block is that browsers pretty much all admit who they themselves actually are and their version somewhere. So we need to get a browser that's lying about those things, too.
