So these features will take approx 4 moths to add to codebase that QT have had for how many years?

Bearing in mind that V5 is apparantly a whole new codebase, these features will have to be recoded from scratch for V5, which will take how long? codebase that the prgrammers are not familiar with? As V5 is already about 6 months late from the original plan, will adding these features to V5 make it even later? or will V5 be a back step in terms of features?

It feels like QT acknowledge that the codebase needs re-writing from scratch for future use, but they don't really want to do it so prefer to keep adding to the V4 code they are used to.

I would much rather these features were just coded into V5, and 4.4 dropped.
