While Coremob Level 0 is a de facto standard which represents an (admittedly rather grim) picture of the current state of the Mobile Web Platform, Coremob Level 1 is a very focused set of features.
Its goal is to enable the highest number of applications short term.
Development of the Coremob Level 1 spec is happening on GitHub.
Please use the CoreMob Tracker to file issues (rather than the GitHub issue tracker). If you have use cases that you wish to see considered, please post them to the list or into the wiki. If you have changes that you would like to see in the draft, don't hesitate to fork it on GitHub and make pull requests.
Quality of Implementation
This list the features susceptible of moving between Coremob Level 1 and Coremob Level 0 depending on how we define the latter.
