I think there is a misunderstanding: The customer will get some software 
use, they don't care if it uses internally Qt X.Y or whatever.

And yes, even if they have Windows 7, they will want a new version of 
the software
with feature X they paid for ;=) They will not even understand why that 
should not
be possible given they have some Windows 7 support contract with 
Microsoft and will
tell you "but it is not EOL for us".

I just wanted to point out that for people building software with Qt, 
this might
mean they will need to maintain two versions of their software to still 
cater all
their Windows customers. Which doubles the pain for them ;=)

And yes, one might argue this is a sole issue for the people building 
such software,
but this issue doesn't arise for them if they use an other toolkit that 
deprecate Windows 7 now.
