I doubt it. That would make it either way too transparent and open, or just a blockchain implementation of a centralized black box.
But yeah, we are likely to see a lot of people using the "blockchain" label for marketing reason, not using the tech for any of it's benefits.
But that's silly even from a technical point of view: if you don't need decentralization and transparency, then a blockchain is a very poor alternative to a blackbox built on postgress.
