[Interest] Qt 5.15 LTS vs Qt 6.2 LTS

In relation to Qt 6, in:

https://www.qt.io/blog/qt6-development-hosts-and-targets

It says that:

"Both *Windows 7 or 8.x* version support will not be available for Qt 6"
"it will no longer be possible to create *UWP* applications on Windows 10."

The latter is a shame, but the former makes me wonder... These platforms 
are still very much active. I understand that Qt will probably still 
"just work", so what does "missing version support" mean?

Also, will Qt receive native themes for windows 11 in Widgets and Quick?

Thanks,
Rui
