No one should use, nor anyone is advised to use, segwit transactions before it is fully activated. Having 2 months or 2 weeks of grace period makes totally no difference in this regard. If anyone tried to use segwit tx during your proposed 2 months grace period, all those txs were still everyone-can-spent. All you are advocating is just stalling the process with no improvement in security. > > I stand by the minimum of 2 months. There is no reason to use BIP9 as it was > coded in an older client.
