The short-term workaround would be to add workable `isInstance` methods on all of our component resources (e.g. in AWSX and EKS), which would be cheap and easy to do. @lukehoban,...

I've opened https://github.com/pulumi/pulumi/issues/10533 to reconsider passing component resource properties to the engine, so that they'd be available in policies (among other things).

There is an old hackathon project to add a Go SDK: https://github.com/pulumi/pulumi-policy/compare/hackweek/go-policy

Hmm, you should be able to have an async validator functio. We have tests for this: https://github.com/pulumi/pulumi-policy/blob/8cef30d09a07d580122c854de1ad0fb193a0521f/sdk/python/lib/test/test_policy.py#L107-L115 I'm not familiar with `aws.pricing.get_product`. Does it return an `Awaitable`? If so, what...

Thanks for opening the issue, Mitch. I'll take a look.
