> You don’t want org1 to have access to the data that user x has access to in org2

Of course not—I'm not sure why you'd think I mean that?

I'm just saying that if I open a link to `https://datadog.com/alert/12389` and `https://datadog.com/alert/12500` and the alerts are for different orgs, my auth cookies should be able to tell that I, as user X, have access to both orgs without having to "switch contexts" or re-auth.
