buildConfigObject() is intended for conditional configuration of the injector. In this case, we don't need it at binding time, so it's cleaner to use a provider method, just like any other object that we need manually construct based on injected things:

@Provides
@Singleton
@ForGlueHiveMetastore
public static RequestHandler2 createRequestHandler(IcebergGlueCatalogConfig config)
{
    return new SkipArchiveRequestHandler(config.isSkipArchive());
}

While using buildConfigObject() works fine, it feels like a "trick" or "cheat" that doesn't generalize to other situations. If we needed anything else from the injector to construct the instance, it wouldn't work.
