Delayed initialization for extension models

Can support be added (it is trivial) to delay the initialization of extension models using the DbgModelClientEx.h client library? There is mention of it within the source but an implementation is lacking. I would consider this critical to the support the library adds as often times you want to initialize data models under certain conditions especially when you have many data models within a single extension. It would be easiest to have this support builtin directly to the provided interfaces already with perhaps a metadata property of "IsDelayed" etc. as well
