 The `OpenFeature::SDK::Provider::MetaProvider` is a utility provider implementation that takes multiple [providers](https://docs.openfeature.dev/docs/specification/sections/providers) for use during flag resolution. This can be helpful when an organization is migrating or consolidating feature flag providers as they transition to OpenFeature. There are usually a combination of internal and vendor providers that are combined together to handle flag resolution. If your organization has different providers for different teams, consider looking at using [domains](https://openfeature.dev/specification/glossary#domain).
