I am very familiar with the rules surrounding the security of systems in our 
intranet. No version of Windows older than 19H2 is allowed anywhere in the 
regular network. They're only allowed in special lab networks, which are 
segregated from the global intranet and have limited ingress and egress.

Yes, older systems exist and many of them are in critical roles. All of them 
are kept in such segregated networks, all of them have special attention paid 
to, and none of them receive any more updates than strictly necessary (because 
that's the *point*). A colleague once joked we have interns younger than the 
Linux kernels running on some of those systems.

Anyway, point was and remains: 6.0 sounded like a good time to cut back on 
supporting old things so we could add new things. If you're going through the 
trouble of Qt's binary compatibility break and a bit of source-compatibility 
break, then it was probably a big enough effort that you'd put off until you 
could drop your older platforms too.
