I get maybe not putting all your chips in SXG basket. I disagree with a bunch of the protest: this seems like a sensible, basic, obvious layered enhancement to the existing web. Safari & Mozia are (as is the mood today) being terrible shits as usual, the regressives.
Contrasting ADX versus SXG just feels so wild, because SXG is a small refinememt to a vast world spanning & complete ecosystem of technology that has already taken over the planet. It directly targets the one complaint you make: http-server centricity, & sets dynamite to that one old bad no-good base. And ADX is an standalone completely isolated alternate world, it's own reality. This tension, whether we need a baseline which is 100% new & novel & redefines the entire problem space on it's own terms, completely from scratch, or whether we can hack & improve & enhance what we have: I dont feel like there's any camp at all left to defend improvememt.
Ideally SXG would be used woth additional user-encryption. User subdomains, eith their own keys would be swell. Turning sites into sites of sites is what SXG really starts to permit. Layering in some .well-known to be more cryptographically portable with identities ks just another small enhancement, just more layering, albeit yet-more-idealism.
Tear it all down, start over... it's the mode. I agree, this debate needs more than HM comments. But this tension & conflict, this view of the world & how it evolves or revolts: it's been trying to make revutions & insist no bounds, nothing today can possibly be good enough for tomorrow. And two plus decades latter, it's made such tiny impact, is so niche.
I accept your snub, getting told im exasperated, but it's for a real reason, it's because these decades have failed to deliver & so few have willingly tried improving what is (Safari & Mozia being a quite vocal modern anchor keeling things in place, a modern astrpturfing shouting class against trying anything, especially). This effort does have the social capital to perhaps emerge & birth something new, but we could also just improve & greatly fix everything that ready is. With minor, layered, small, principled enhancements.
