I am keeping an updated patch branch for ExtJS 4 on https://github.com/One-com/Ext-JS-4/tree/denormalized_4.0.2a
The probably outdated Sancha Touch patch branch is here: https://github.com/One-com/Sencha-Touch/tree/denormalized_1.1.0
Also I have started this forum thread on the subject: http://www.sencha.com/forum/showthread.php?127547-Sencha-Platform-denormalized-Data-patch
