Still, I think it makes sense that Qt 6 requires Windows 10. New development and legacy support are always at odds.
If customers want new software, then they must accept that it has modern requirements. Same situation for continued development and evolution of existing software.
In situations where support for legacy systems is more important than new development, then existing applications can just continue to use Qt 5. I don't see how it would make sense to migrate to Qt 6 in this situation.
