I agree, we are also planning to take advantage of it for some specific 
use-cases in future.

They will come handy in future. I plan to use it in future and we can 
skip the API/ABI breakage, if the placeholder are present

I have another suggestions w.r.t iv, aad, digest etc. Why not put them 
in a structure, so that you will

be able to add/remove the variable without breaking the API prototype.
