It's actually not that bad of an idea. Since there's already people who are doing their little "BRC-20" thing with Ordinals which seem to be unnecessarily complex transactions, at least such a protocol (especially being proposed by someone like Casey, which means that while adoption would remain voluntary, it actually stands a good chance of having people decide to adopt it). It's pretty apparent, at least in my opinion, that ordinals/inscriptions aren't going anywhere; neither are the other implementations of such technology that people are dreaming up. Its also my opinion that this will continue to go on and the people who are participating in these activities do not give a shit about the various arguments certain purists here would make against it. That being the case, I think it's actually a pretty wise/prudent thing to push for.
