COEP: credentialless. Isolation w/o Opt-In?
Credentialless is a Cross-Origin-Embedder-Policy (COEP) variant. Similarly to require-corp, it can be used to enable cross-origin-isolation. Contrary to require-corp, it is easier to deploy, instead of requiring a Cross-Origin-Resource-Policy (CORP) header for every no-cors subresources, COEP:credentialless is requesting them without credentials.
