    IMHO the licensing change will happen as Sencha is losing market share to competitors who offer a single developer license. You can't ignore the competition for too long.

    Yes, Deft works with Ext JS 6.

    However, there's little incentive to use it since most of its features (except injection) are now available in Ext JS.

    I don't see that the refHolder variable is used in the onRemoved method in the Component class.
    It's declared, but not used.

    This is a minor code issue. The refHolder local variable is not used, so it'd be better to remove it. Are we supposed to report issues of this kind? I'm trying to be helpful.

  16. Setting property to null before deleting it

    ext-6.2.1.121
    I'm looking at this code fragment and I don't quite understand why the property xhr is set to null before deleting.
    This seems redundant(?).

    I think the initConfig line is redundant since the observable mixin includes this call.

    mixins: [
    'Ext.mixin.Observable'
