Well, Qt 4.8 wasn't split source neither. I know distributions don't like it very much, but at the same time I don't think we should delay the beta further because of this.

Split source packages also should lead to split binary package (aka an online installer). 

But in any case, I still don't see this as an absolute must have for 5.0. It is certainly more important to get a release out then delaying another month to implement split source packaging.

The main problem implementing split source packages is documentation. Currently this still requires a monolithic source package, and until we have gotten that one modularised we simply can't do it.
