Nested activities and Android Fragments

[Y2i]

Honeycomb introduced Fragments that represent behaviors of portions of user interface.  Fragments were specifically created for tablets that have larger screens than regular phones.  They play nicely with the Back button by introducing back stacks that are managed by the hosting activities. Fragments simplify development of applications that run on different screen sizes: they can be combined in a single activity to build a multi-pane UI or can be reused in multiple activities with single-pane UIs.

This forum has had many discussions related to nested activities.  Android fragments are exactly what GWT is missing to support this feature. Since GWT applications primarily run on large screens, it would be nice to have analogous capabilities available to Android tablet developers.  

Are the plans to incorporate something like this to GWT?
