Thanks Murch appreciate the feedback
The goal here isn’t to condone or support data carriage in Bitcoin, although OP_RETURN does that despite being undercut by witness, but to simply acknowledge data exists and treat it accordingly as a structurally addressable region which transfers resource control to node operators as we have discussed. I understand your doubts that this will take off, and that’s fine. If the debate continues, which i presume it will, this is available for further discussion until it is superceded by a better proposal, or the whole issue disappears forever.
As for next steps, i will update the BIP with the changes as discussed here, and then make a PR to the bips repo? or widen the conversation to the mailing list?
