I also wonder if this the purpose of `initialize`/`getData` in

ComponentResource

? So that it's easier to make construction pick between "create something new" and "reference something existing"?

awsx.ec2.Vpc

seems to have this sort of pattern but again open to any feedback/suggestions. There is https://github.com/pulumi/pulumi/issues/4133 on GitHub but it's not really gone anywhere yet. Thanks!
