No, it is not. It has hard wired bindings from certain names to morphic adapters, but only if you don't actually specify the target calss.
In other words, if in your #specLayout you specify a name that has a binding, then the binding will be used; if there is no such binding, then the class will be instantiated directly.

So for example if you specify:
* LabelAdapter -> there is binding from LabelAdapter to MorphicLabelAdapter, so MorphicLabelAdapter will be instantiated
* MorphicLabelAdapter -> there are no bindings for this name, so it will be instantiated directly
* CocoaLabelAdapter -> there are no bindings for this name, so it will be instantiated directly

But we should not reference directly platform specific widgets when we define spec layout. Otherwise we will be forced to copy every layout method (like #defaultSpec) for each platform.

And it breaks goal of Spec to be able open application with different backends without code modification.

I am sure you know what I wrote. So probably I not understand what you mean.
