Why should iWatch jailbreak

Apple recently released watchOS 4.1 as the latest version and watchOS 4.2 is on beta stage. It has introduced brand new features as well as improved features via this version. However, most important missing functions were not included yet. So, jailbreak is the way getting it. But it has no any jailbreak hint about watchOS 4 until now. When compare with iOS 11 & higher versions,watchOS 4 jailbreak intervention is insufficient.
WatchOS 3
iWatch (Apple Watch) was introduced without some most necessary functions such as Web browsing, custom watch faces, advanced clock types.
Cydia offers many functions to iDevices as the most popular 3rd party app store. So jailbreak is the only option to get those missing functions as jailbreak tweaks to iWatch.
Reasons for iWatch jailbreak
Stock apps customization.
Watch faces changes.
More themes.
Custom elements complications.
