Well ... Qt developers should decide about their style of development.
If Qt-developers gathered and decided that style is "it is not a bug it is a feature" then I totally support
decision to remove -NO-RTTI from the whole Qt because RTTI compiler feature was occasionally used

This is same question as why Qt have -no-feature-xxx flags.
For me support of specifics of new major Windows OS release is worth calling it "feature".

Who can give you any real reason to call anything a feature or an update? I think you understand that.
If there were some publicly known principles what is feature for Qt and what is Qt update then we could decide if some reason is good enough or not.

In current situation Qt-lib is now the only option is only to share my vision : using special features of newer major version of Windows looks like "feature" of Qt lib (for me)
In discussed case compatibility with SDK from previous windows version was lost.

I am not sure that this is error in code. Most probably I do something wrong. At least somehow Qt company is able to build Qt 5.8.0 RC with vc2013.
But it is not clear to me how this problem was avoided. Does anyone knows that?
