I noticed that

pulumi up

now has

--exclude

flag - SUPER! However, any chance it does not excludes deletions? (when I

--exclude "**pubsub**"

I noticed that new pubsub items are not created, but existing ones are still being deleted)

That sounds like a bug, it is meant to be the opposite of --targets and untargetted resources wouldn't be deleted. Raise an issue at github.com/pulumi/pulumi
