It is not clear if the decision was to take out the permission management altogether when the powers that be weighted in on the issue.
Also found a couple of G+ posts where people ask about this but haven't got any answer, e.g.:
I wonder if something like is what transpired with WhisperCore:
It was developed by the same people behind RedPhone and TextSecure.
There are alternatives, like PDroid, but it would be most useful if at least permission management was included out of the box, putting control back in the hands of the user.
