Deep validation of Sencha Touch models

I can't find anything relating to this in the official Sencha Touch documentation or source code, have you been in touch with them regarding them possibility of them implementing the same behaviour (or just including your function into their code base..)?

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The probably outdated Sancha Touch patch branch is here: https://github.com/One-com/Sencha-Touch/tree/denormalized_1.1.0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
