Well, that explains why you seem to think that continuing support for old platforms while adding support for new ones is trivial (“it just works”), costs nothing (in terms of infrastructure, cost of delay for implementing new changes and using new capabilities), and should at the very least done for free ;)

When you have to pay people salary and have customers that pay for a supported product, then that looks a bit different, both in terms of effort and on the balance sheet.

I suppose what you describe as your QA process will about the level of QA we are going to have for Windows 7 in that Qt 6 fork then. I’d assume that you and your users/testers are going to be fine with it ;P
