This follows our conservative approach to make the worst-case validation times no worse than they are presently, on any viable hardware. The remaining two BIPs (OP_TX, and new opcodes) are not submitted: they are mainly useful to provide a roadmap what functional gaps remain after the script extensions, and do not have full implementations. Cheers! Rusty & Julian.
