IMHO that is a really dumb assumption. Different platforms have 
different capabilities. Different projects have different levels of 
support on different platforms.

I understand that these tools are trying to create a cross-platform 
environment, but there has to be cases where this is (for good reasons) 
not possible. At the very least they should be able to see if there is a 
set of versions that is able to meet the cross-platform requirements 
(which there is in this case).

The reason the Windows wheels are based on an older version of Qt is 
that I haven’t yet put the effort into building from source. I plan to 
get around to it at some point but it’s not a priority.
