This is perhaps more important in the age of AI agents, but before we can tackle all these fancy ZKP constructs in the mainstream — we have to, as the industry (and so far consistently failed to) — implement Zanzibar, or whatever ReBAC, and maybe ZKP stuff could "sneak in" that way, in the form of zero-knowledge warrants, or whatnot. Unfortunately, even though it works consumption-wise, it's fundamentally at odds on the provider side.
The providers are clutching their OLAP like pearls! :-)
