I think they should give us the option to create watch faces, but don't care about it much. It's very far down my priority list of what I want from Apple Watch.

I think they should give us the option to create watch faces, but don't care about it much. It's very far down my priority list of what I want from Apple Watch. As for the reasons why they don't, my speculation is the following (I'm not defending them): They are worried about custom watch faces that might perform poorly or draw too much battery. Watch is a challenging platform to develop for as watchOS is very protective of its resources and won't hesitate to kill your app. But Apple probably doesn't want to kill the watch face and at the same time doesn't trust the developers to develop their watch faces to Apple's standard.
