Beta software on backports PPA?

I'm using 10.04 and had the backports PPA enabled. This caused the
installation of KDE 4.5, which uses Qt 4.7 (in beta phase)

There are lots of breakage after the upgrade.

My questions are:

1. Is it okay to push beta versions of essential components through the
backports PPA?

2. What's the rationale for using a beta version of Qt instead of the
stable one which, AFAIK, is far more stable and tested with KDE 4.5?

3. Is it possible to downgrade to KDE 4.4.x without major surgery?
