If we keep the state of making almost no fixes, why would it matter if Qt Quick 1 is not included in the Qt 5.6? Those who need it can take it from the repository and use with their app, even if we do not include the module any more in the official release packages.

The thing is that since the beginning of Qt 5 we have been constantly adding things and not removing the parts that are less used (and deprecated). Even though one might think it takes very little effort to keep things around, the aggregate effort is significant. 

There are many great new things and improvements we could bring into Qt, but now a lot of time goes into keeping old parts afloat. If someone needs to use an old module, why not do it with a Qt version that supports it? Same goes to platforms and compilers - it is not feasible to properly support all upcoming and old versions.
