Are there any plans for a MIT-licensed Ext Touch Core (similar to Ext Core, but for mobile devices only) in the pipeline?

I'm in the midst of developing an iPad app using just Ext Core now, and while it works well for most purposes, it would be really neat to have all the non-mobile fluff from Ext Core removed, and have all the niceties (like the Ext.TouchEventManager) from Ext Touch included.
