Why would you do that (and bump this old thread) except for pure trolling purposes? Considering that fact that secp256r1 has unexplainable mystery parameters I can't imagine anyone outside of the NSA promoting it.
Because I haven't been able to piece together that the issue brought in this thread was fully resolved (maybe I missed something / read too quickly), and wanted to expose the matter at hand to more eyes.
Since then I also posted
to reddit and via it found
this other bitcointalk thread that sheds more light on the matter.
No trolling intended I assure you.
