This is absolutely true. But what does it mean to keep using an outdated version in a connected system? How to ensure that the system remains secure? How to be able to bring new functionality (if / when) required by the customers? These issues may not happen for every system, but more and more will need to consider these. By being able to update the version of Qt framework regularly it becomes easier to address these issues, but of course there always are pro and cons. When creating a system, it is beneficial to make it so that it is feasible to regularly update it's components, including the Qt framework.

Yours,
