The Vercel breach: OAuth attack exposes risk in platform environment variables

Security-by-obfuscation is ridiculed but I'm a firm believer that preventing yourself from getting owned when someone is able to type 3 letters `env` is a worthy layer of defense. Even if those same secrets are unencrypted somewhere else on the same system, at least make them spend a bunch of time crawling through files and such.
I don't see how its necessarily relevant to this attack though. These guys were storing creds in clear and assuming actors within their network were "safe", weren't they?
Designing for provider-side compromise is very hard because that's the whole point of trust...

It's ridiculed because its no protection on its own when an attacker is motivated. Its fine to add as an additional layer though if you want to make your space mildly custom to protect against broader attacks. I don't see how its necessarily relevant to this attack though.

My point is sensitive secrets should literally never be exported into the process environment, they should be pulled directly into application memory from a file or secrets manager.
It would still be a bad compromise either way, but you have a fighting chance of limiting the blast radius if you aren't serving secrets to attackers on an env platter, which could be the first three characters they type once establishing access.
"Effective defense requires architectural change: treating OAuth apps as third‑party vendors, eliminating long‑lived platform secrets, and designing for the assumption of provider‑side compromise." Designing for provider-side compromise is very hard because that's the whole point of trust...
Do any marketplaces have a good approach here? I know Cloudflare, after their similar Salesloft issue, has proposed proxying all 3rd party OAuth and API traffic through them. But that feels a little bit like trading one threat vector for another.
Other than standard good practices like narrow scopes, shorter expirations, maybe OAuth Client secret rotation, etc, I'm not sure what else can be done. Maybe allowlisting IP addresses that the requests associated with a given client can come from?
