I understand your point.

When I initially looked at trusted key implementation, it seemed to be
tightly coupled to use TPM device. So I implemented a parallel
implementation to get initial feedback (functionality-wise) on this
new approach.

I will work on abstraction of trusted key apis to use either approach.
But is it fine with you if I send if I send a separate RFC patch for
abstraction and later once reviewed I will incorporate that patch in
this patch-set.

It will be really helpful if you could help to test that abstraction
patch with a real TPM device as I doesn't posses one to test.
