If you're parsing this info into the OS column, you should probably display this info in there at least with a note, or something like "Windows 10/11", "macOS 10.5 or newer"
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.
Windows 11 uses the same 10.0 as Windows 10, the difference shifted to the "build number", which feels a bit weird cause now 10.0.19045 (Win10 22H2) was released a year later than 10.0.22000 (Win11 21H2)...
