The answer is actually pretty easy for this:
- It’s how Google have designed Android 4.4 to be.
- Google have with 4.4 introduced design guidelines for makers using Google Android, more or less “if you want to use android (including Play store, this is the conditions for that”. I think that it’s for users to not be confused over what Android is and so on. HTC have with current Sense version moved closer to how Google designed Android.
